   Item 1 - Description of Business

   a.   General Development of Business
<PAGE>
        (i)  General

        VASCO Data Security International, Inc., a Delaware  corporation
   (the "Company" or "VASCO"), was incorporated  on July 15, 1997.   Its
   executive office  is located  at 1901 South  Meyers Road,  Suite 210,
   Oakbrook Terrace, Illinois 60181; (630) 932-8844.  On March 20, 1998,
   the Company's Common Stock,  $.001 par value  per share (the  "Common
   Stock") was  approved for  trading on  the Over-the-Counter  Bulletin
   Board system with the symbol: VDSI.
                       
             This  report  contains  the  following  trademarks  of  the
   Company, some  of  which  are registered:  VASCO,  AccessKey,  VACMan
   Server and VACMan/CryptaPak, AuthentiCard and Digipass.

   The  Company,  through  its  operating  subsidiaries,   designs,
   develops, markets  and  supports open  standards-based  hardware  and
   software  security  systems  which   manage  and  secure  access   to
   information assets.

        (ii) 1998 Reorganization - Exchange Offer

        The Company  was organized  in 1997  as  a subsidiary  of  VASCO
   Corp., a  Delaware  corporation  ("VASCO Corp.").    Pursuant  to  an
   exchange offer (the "Exchange Offer")  by the Company for  securities
   of VASCO  Corp.  that  was completed  March  11,  1998,  the  Company
   acquired 97.7%  of the  common stock  of VASCO  Corp.   Consequently,
   VASCO Corp. is now  a subsidiary of the  Company, with the  remaining
   2.3% of VASCO Corp. shareholders representing a minority interest.

        For the purposes of  the discussion of  the general business  of
   the Company below, references to the  "Company" shall refer to  VASCO
   Corp. for periods prior  to March 11, 1998,  the date on which  VASCO
   Corp. became a 97.7% owned subsidiary of VASCO.

        (iii)     Prior Organizational History

        The Company is essentially a  holding company that conducts  its
   business through  operating subsidiaries  in  the United  States  and
   Europe.

        The Company presently has two operating subsidiaries. VASCO Data
   Security, Inc.  ("VDS"),  a  Delaware  corporation  headquartered  in
   Oakbrook Terrace, Illinois,  is owned directly  by VASCO  Corp.   The
   Company's  other  operating  subsidiary,  VASCO  Data  Security NV/SA
   ("VDS NV/SA"), is a Belgian corporation headquartered in a suburb  of
   Brussels, Belgium.  VDS NV/SA  is  owned by  VASCO  Corp.'s  European
   holding company subsidiary, VASCO  Data Security Europe SA  ("VDSE").
   VDS and VDS NV/SA are engaged  in the design, development,  marketing
   and support  of  open  standards-based hardware  and  software  based
   security systems  which manage  and secure  access to  data and  also
   provide products that permit their customers to encrypt data.

   [Organization Chart appears here]

   *  All share are held  by the parent corporation, except that  shares
   representing less than 1% are held by T. Kendall Hunt.
<PAGE>
        VDS.  In November  1989, a Utah  corporate predecessor of  VASCO
   Corp. acquired  an  option  to purchase  a  controlling  interest  in
   ThumbScan, Inc.  ("ThumbScan"). VASCO  Corp. acquired  a  controlling
   interest in ThumbScan  in January 1991,  and in  December 1991  VASCO
   Corp.  increased  its  holdings  in  ThumbScan.  VASCO   subsequently
   acquired the remaining shares of  ThumbScan. In July 1993,  ThumbScan
   was renamed VASCO Data Security, Inc.

        VDS NV/SA.  VASCO  Data  Security   NV/SA  ("VDS NV/SA")  is   a
   combination  of  two  European  companies  (Lintel  Security  NV  and
   Digipass SA) acquired  by VASCO  Corp., through  VDSE, in  1996,  and
   accounts for  a substantial  portion  of VASCO  Corp.'s  consolidated
   revenues.

        Acquisition of Lintel Security.   In 1996,  VASCO Corp. began  a
   significant expansion of its computer security business by  acquiring
   a 15%  interest in  Lintel Security  NV ("Lintel  Security").  Lintel
   Security, a newly formed Belgian corporation, concurrently  purchased
   from Lintel NV,  a Brussels,  Belgium based  company, certain  assets
   associated with  the  development  of security  tokens  and  security
   technologies for personal  computers ("PCs"),  computer networks  and
   telecommunications systems using Data Encryption Standard ("DES") and
   Rivest, Shamir, Adelman ("RSA") cryptographic algorithms. VASCO Corp.
   acquired the remaining 85%  of Lintel Security in  June 1996. At  the
   time  of  acquisition  of  Lintel NV's  assets  by  Lintel  Security,
   Lintel NV was a  competitor of VASCO  Corp. in  Europe. The  purchase
   price paid for  Lintel Security was  approximately $4.4 million,  and
   was paid in cash, shares of VASCO Corp. common stock, and VASCO Corp.
   warrants and convertible notes.

        Acquisition of Digipass.  In July 1996, VASCO Corp. acquired the
   stock of Digipass SA ("Digipass") for an aggregate purchase price  of
   $8.2 million. Digipass,  based in a  suburb of Brussels,  was also  a
   developer of  security  tokens  and security  technologies  for  PCs,
   computer  networks  and  telecommunications  systems  using  the  DES
   cryptographic algorithm. At the time  of acquisition, Digipass was  a
   competitor of VASCO Corp. in Europe.

        Prior to VASCO Corp.'s  acquisition of Digipass, certain  assets
   and liabilities of the interactive voice response ("IVR") business of
   Digiline SA, an integrator  of IVR  products based  in Belgium,  were
   transferred to Digipass. Digipass'  IVR products were used  primarily
   in telebanking applications and incorporate authentication and access
   control technology. During 1997, VDS NV/SA entered into an  agreement
   to sell the IVR business to Siemens Societe Anonyme for approximately
   $200,000.

        In January  1997,  Digipass  changed its  name  to  "VASCO  Data
   Security NV/SA."    Concurrent  with  this  event  Lintel  Security's
   operations were  consolidated with  those of  VDS NV/SA  at a  single
   location near Brussels.
<PAGE>
        VASCO  Corp.'s  original  business  was  providing   consulting,
   training and software services to companies and government  agencies.
   These services were marketed as VASCO Performance Systems ("VPS"). In
   1996,  management  determined  that  VASCO  Corp.  should  focus  its
   energies and  resources  on  the data  security  industry,  where  it
   believed   significant   growth   and   profit   potential   existed.
   Accordingly, on August 20, 1996, VASCO  Corp. sold the assets of  VPS
   to  Wizdom  Systems,  Inc.  and  withdrew  from  the  consulting  and
   technical training business.


   b.1  Financial Information about Industry Segments

        During each  of the  last three  fiscal years,  the Company  has
   operated in only one industry segment.

   b.2  Financial  Information   Relating   to  Foreign   and   Domestic
   Operations and Export Sales

        See Note  10 to  VASCO CORP.   Notes  to Consolidated  Financial
   Statements  for  certain  information  about  foreign  and   domestic
   operations and export sales.

   c.   Narrative Description of Business

        (i)  General

        The  Company  designs,  develops,  markets  and  supports   open
   standards-based hardware and software  security systems which  manage
   and secure  access  to  information assets.  The  Company's  hardware
   products include time-synchronous  response only,  challenge/response
   and time-synchronous challenge/response user authentication  devices,
   some of which incorporate an electronic digital signature feature  to
   guarantee the  integrity of  data  transmissions. These  devices  are
   commonly referred to as security tokens.

        The Company's security tokens are based upon its core encryption
   technology, which utilizes two widely known and accepted  algorithms,
   DES and  RSA. The  Company's Cryptech  division produces  high  speed
   hardware and software  encryption products used  both internally  for
   its security tokens and for original equipment manufacturers  ("OEM")
   vendors requiring  real time  encryption services.  In addition,  the
   Company has  introduced  a smartcard  security  token that  uses  the
   challenge/response  mode  and  the X.509  certificate  authentication
   standard.

        The Company's security tokens are designed  to be used with  the
   VASCO Access  Control Manager  ("VACMan") server  software or  to  be
   integrated  directly  into  applications.  Together,  the   Company's
   software and  hardware  products  provide  what  it  believes  is  an
   economical   state-of-the-art   authentication,   authorization   and
   accounting security system.

        The Company had  sold over 2.0 million  security token  devices,
   its primary  product line,  as of  December 31, 1997.  The  Company's
   security products  are sold  primarily to  value-added resellers  and
   distributors, and to a lesser extent end-users.
<PAGE>
        The Company has embarked upon  an aggressive campaign to  expand
   its distributor and reseller network. Distributors and resellers that
   have  entered   into   agreements  with   the   Company's   operating
   subsidiaries include,  among  others,  Concord-Eracom  Nederland  BV,
   Protect Data Norge AS, Sirnet AB, All Tech Data Systems, Inc.,  Clark
   Data Systems, Inc., HUCOM, Inc. and SEI Information Technology.

        Representative  end-users  of  the  Company's  products  include
   ABN-AMRO Bank, Generale Bank, Banque Paribas Belgique S.A., Rabobank,
   S-E Banken, AMP Inc., Volvo Data North America, Inc., France Telecom,
   Manitoba Telephone, Andrew Corp., and Molson Breweries.

        (ii) Industry Background

        The Data Security  Industry.   The increasing  use and  reliance
   upon proprietary or confidential  data by businesses, government  and
   educational  institutions  that  is  accessible  remotely  by  users,
   together with  the  growth  in electronic  commerce,  has  made  data
   security a paramount concern. The Company believes that data security
   concerns  will  spur  significant  growth  in  the  demand  for  both
   enterprise and consumer security solutions.

        Enterprise Security.  With the advent of personal computers  and
   distributed systems  in  the form  of  wide area  networks  ("WANs"),
   intranets which  connect users  in disparate  facilities, local  area
   networks ("LANs"), which connect users  located in a single  facility
   and the  public network  known as  the Internet/World  Wide Web  (the
   "Internet"), and other  direct electronic  links, many  organizations
   have implemented applications  to enable their  work force and  third
   parties, including vendors,  suppliers and customers,  to access  and
   exchange data. As a  result of the increased  number of users  having
   direct and remote access to enterprise networks and data, including a
   growing number  of  mobile  computer  users  and  telecommuters  that
   perform some  or  all  of  their  work  from  home  or  other  remote
   locations, data has  become increasingly  vulnerable to  unauthorized
   access.

        Unauthorized access can range from  users who are authorized  to
   access portions  of  an enterprise's  computing  resources  accessing
   unauthorized portions,  to  hackers  who have  no  legitimate  access
   breaking  into  a  network  and  stealing  or  corrupting  data.  The
   consequences  of  such  unauthorized  access,  which  can  often   go
   undetected, can range from theft of proprietary information or  other
   assets to the alteration or destruction  of stored data. As a  result
   of  unauthorized   access  stemming   from  the   increased  use   of
   enterprise-wide computing  and remote  access, network  security  has
   become a primary concern to most companies that use and rely on data.
   This increased attention to data  security has stimulated demand  for
   data security  products. The  Company believes  that enterprises  are
   seeking solutions which will continue to allow them to expand  access
   to data while maintaining adequate security.
<PAGE>
        Consumer Security.  In addition to the need for  enterprise-wide
   security, the proliferation of PCs in both home and office,  combined
   with widespread  access to  the  Internet, have  created  significant
   opportunities  for  electronic  commerce  such  as  electronic   bill
   payment, home banking and home shopping. All of these activities  are
   primarily based  on  the  use  of  the  Internet  and,  according  to
   published reports,  the  growth  in  the  number  of  Internet  users
   worldwide is expected  to increase from  approximately 28 million  in
   1996 to approximately 175 million by the end of 2001.

        The public generally perceives that there is a risk involved  in
   using credit  cards  to make  purchases  via the  Internet  and  this
   perception has hampered the development of consumer-based  electronic
   commerce. Accordingly, the Company believes that successful expansion
   of  electronic  commerce  requires  the  implementation  of  improved
   security measures,  which  accurately  identify  users  and  reliably
   encrypt data transmissions over the  Internet.  This is  particularly
   true in North America,  which has generally  lagged behind Europe  in
   this area.

        (iii)     Products

             (A)  Current Data Security Solutions

        Data security and secured  access to on-line commerce  generally
   consist of five components:

             Encryption:     Maintains   data  privacy   by   converting
        information  into  an  unreadable  pattern  and  allowing   only
        authorized parties  to decrypt  the  data. Encryption  can  also
        maintain data  integrity  by  creating  digital  signatures  for
        transmitted data, enabling  the recipient to  check whether  the
        data was changed since or during transmission.


             Identification  and   Authentication:     Serves   as   the
        foundation for  other security  mechanisms by  verifying that  a
        user  is  who  he  or  she  claims  to  be.  Identification  and
        authentication mechanisms  are  often employed  with  encryption
        tools to authenticate users, to determine the proper  encryption
        key for  encrypting/decrypting  data,  or  to  enable  users  to
        digitally "sign" or verify the integrity of transmitted data.

             Access Control:  Includes  firewalls, which limit a  user's
        access to data to only that  data which he or she is  authorized
        to access, and authorization and accounting systems, which  also
        limit access to data and keep track of a user's activities after
        access has been granted. 
             Anti-Virus:  Programs  that scan  for and,  in many  cases,
        remove destructive computer programs  known as computer  viruses
        that can become imbedded into programs residing on a computer.

             Administration and Management  Tools:   Set, implement  and
        monitor security  policies, the  access  to which  is  typically
        regulated by access control  systems. These tools are  extremely
        important to the overall effectiveness of a security system.
<PAGE>
        The most effective security policies employ most, if not all, of
   these five  components.  However,  most companies  only  implement  a
   patchwork combination of these components, which can result in  their
   security systems being compromised.

        Historically, the Company's primary products have been  security
   tokens. Security tokens  are an integral  part of identification  and
   authentication systems, which  in turn  serve as  the foundation  for
   each of the  five components of  data security outlined  above.   The
   Company has sought to leverage its identification and  authentication
   expertise by expanding  its product  offerings to  include the  other
   components of data security, in each case incorporating the Company's
   security tokens.  The  Company  has  sought  to  expand  its  product
   offerings to reach  its ultimate goal  of supplying a  full range  of
   security products for integrated, enterprise-wide security solutions,
   which will meet the needs of the emerging data security market.

        Identification   and   Authentication.      Identification   and
   authentication systems provide the foundation for security systems by
   validating the identity of each user attempting to access information
   or data  contained in  a system,  regardless  of location.  The  most
   common use  of  an identification  and  authentication device  is  to
   authenticate local and  remote users who  have established a  network
   connection to a company's  computer network. Authentication is  often
   done in conjunction with a firewall to authenticate internal users of
   stand-alone  PCs  on  networks  or  to  authenticate  customers   and
   suppliers who have been granted access to a restricted portion of the
   company's data or other information.

        There are three basic methods used  to authenticate a user.  The
   first method identifies  who the user  is, utilizing a  hard-to-forge
   physical attribute such as the user's fingerprints, voice patterns or
   eye retina  patterns.  In  each  case,  the  physical  attribute,  or
   biometric, must  be  capable of  being  scanned and  converted  to  a
   digital document.  While  biometric devices  offer  a high  level  of
   authentication,  they  are  susceptible  to  replay  attacks.  Replay
   attacks collect samples of a  user's biometric "print" (i.e.,  voice,
   finger, retina)  and  then replay  the  "print" to  access  a  target
   system. Furthermore, current technology requires additional  hardware
   to acquire,  or  read,  the biometric  "print."  The  added  hardware
   presents two challenges for biometric solutions: one is the cost  and
   the second is installation and maintenance.

        The second authentication  method is identifying  what the  user
   knows, usually a password known only to the specific user. Passwords,
   while easy to use, are also the least secure because they tend to  be
   short and  static,  and  are  often  transmitted  without  encryption
   ("clear text"). As a result, passwords are vulnerable to decoding  or
   observation and subsequent use by unauthorized persons. Once a user's
   password has been compromised, the  integrity of the entire  computer
   network can be compromised.

   The third authentication  method identifies what  the user  has,
   generally a  physical  device  or token  intended  for  use  by  that
   specific user. Tokens  are small devices  ranging from simple  credit
   card-like devices  to  more  complex devices  capable  of  generating
   time-synchronized challenge/response access codes. Early examples  of
   simple tokens include building access passes.

        Certain token-based systems require both possession of the token
   itself and a  PIN to  indicate that  the token  is being  used by  an
   authorized  user.  Such  an  approach,  referred  to  as   two-factor
   authentication, provides  much greater  security than  single  factor
   systems such  as passwords  or simple  possession of  a token.  Early
   implementations of two-factor authentication include automatic teller
   machine ("ATM") cards. ATM cards require the user to possess the card
   and to know the PIN before  engaging in the transaction. The  Company
   believes that the use of the two-factor authentication system is  the
   optimal solution for reliable computer  and network security and  has
   targeted its products toward this end.

        Security  Tokens.    A  security  token  is  a  small,  portable
   computing device designed to generate  a one-time password. They  are
   normally difficult to counterfeit and  are assigned to an  individual
   user. The user  transmits a token-generated  password, along with  an
   assigned user  ID, to  a host  or authentication  server,  requesting
   access, generally to a network. Token-generated passwords are derived
   from a secret  key or  seed value.  An authentication  server on  the
   network receives and decrypts the token password with a corresponding
   decryption key, validates the user, and (if validated) grants access.
   Currently    available    security     tokens    are     event-based,
   time-synchronous, response only or challenge/response based.

        Event-based tokens have the same list of predetermined passwords
   as the authentication server. Passwords are generated by the token in
   a predetermined  manner, which  is expected  by the  server, and  the
   passwords remain valid for indefinite periods of time. As a result of
   the passwords being  generated from  a predetermined  list and  their
   ease of calculation by unauthorized users, event-based tokens are the
   easiest to compromise.

        Time-synchronous tokens  require the  authentication server  and
   the token to be password time-synchronous. When used, the token  will
   calculate and display a password using a stored secret seed value and
   the current  time of  day. The  server  then determines  whether  the
   password received is correct for the time frame that it was used  in.
   The principal  drawbacks for  time-synchronous tokens  are  extensive
   maintenance with respect to clock synchronization and the possibility
   of multiple uses within the specified time frame. Usually, steps  are
   taken  to  limit  the   re-use  of  a   password,  however,  when   a
   time-synchronous token is defined to multiple authentication servers,
   a common practice, then there is  a risk of a password being  re-used
   to access other servers. Nevertheless, these devices provide a higher
   level of security than event-based tokens.

        Response only tokens use either an "event" or time to  calculate
   the response only password. Response only tokens require the user  to
   activate the token and read the password.
<PAGE>
        Challenge/response tokens provide the highest level of security.
   The authentication server responds to a request for access by issuing
   a  randomly  generated  challenge  in  the  form  of  a  numeric   or
   alphanumeric sequence. The token, using  its embedded seed value,  or
   key, encrypts  the challenge.  The result  is an  encrypted  response
   which the user then transmits back  to the authentication server  via
   the user's PC keyboard. The server in turn retrieves the key that has
   been assigned to that user and decrypts the user's response. Assuming
   a match exists, the server authenticates the user and grants access.

        As with  time-synchronous tokens,  challenge/response tokens  do
   not transmit  an  encryption key.  However,  unlike  time-synchronous
   tokens, passwords of challenge/response tokens are one-time passwords
   that can never be  re-used. In addition, there  is no opportunity  to
   initiate a second, illegal  session with a challenge/response  token.
   Each attempt  at access  is  accompanied by  a  new challenge  and  a
   correspondingly unique password response.

        Although  challenge/response  tokens   generate  true   one-time
   passwords, it is possible  to compromise the  internal seed value  of
   pure challenge/response tokens that only use  the seed value and  the
   challenge to calculate the response.

        Time synchronous challenge/response  tokens can be  used to  add
   another variable  in the  calculation of  the one-time  password.  In
   addition to the  secret seed value  and the challenge  from the  host
   server, the time of  day can be used.  Because there is a  challenge,
   the time synchronization does not have to be nearly as exact as  with
   time-synchronous tokens. When time is used  as an input variable  for
   challenge response  tokens,  it  is  impossible,  with  today's  most
   advanced computers,  to  use  dictionary attacks  to  compromise  the
   token.

        Smartcards.   Smartcards  are  credit card  sized  devices  that
   contain an  embedded  microprocessor,  memory  and  secure  operating
   system. Smartcards have been used in many applications, for  example,
   as stored value  cards, either for  making general  purchases or  for
   specific applications such  as prepaid calling  cards, and as  health
   care cards, which are used to store patient and provider  information
   and records.  Major smartcard  chip  and card  manufacturers  include
   Gemplus SA, Schlumberger Ltd., Philips Electronics N.V., Siemens A.G.
   and Groupe Francois Charles  Oberthur (FCO). These vendors,  together
   with cryptographic vendors, have  worked to make smartcard  standards
   compatible with cryptographic standards to offer a security  solution
   with authentication and digital signature capabilities.

              (B) The Company's Solution

        To date, most approaches to  network security have been  limited
   in scope  and  have  failed  to  address  critical  aspects  of  data
   security. The Company believes that the computer security industry is
   moving away from incremental  or point solutions to  enterprise-wide,
   fully integrated solutions.  The Company believes  that an  effective
<PAGE>
   enterprise-wide solution must address and assimilate issues  relating
   to the  following:  ease  of  use  and  administration,  reliability,
   interoperability  with  heterogeneous  enterprise  environments   and
   existing customer applications,  and scaleability.  The Company  also
   believes that in order to capitalize on this growing market need  for
   enterprise-wide security  solutions, network  security products  must
   embody  both  hardware  and   software  components  and  provide   an
   industry-accepted, open standards-based solution.

        Accordingly, the Company has  adopted the following approach  to
   data security:

             (i)    In  designing  its   products,  it  has  sought   to
        incorporate all industry-accepted, open, non-proprietary, remote
        access protocols,  such  as  RADIUS and  TACACS+.  This  permits
        interoperability between the  Company's security token  products
        and leading remote access servers. 
             (ii)  It  has incorporated the  two most  widely known  and
        accepted algorithms  _ the  DES and  RSA algorithms  _ into  its
        products  and   has   sought   to   refine   its   offering   of
        single-function,  multi-function,  challenge/response,  response
        only and digital signature security token products. The  Company
        believes that its combination of software and hardware  products
        provide security with added speed, cryptographic  functionality,
        reliability and  flexibility not  attainable with  software-only
        programs.  Its   products  provide   two-factor   authentication
        requiring the authorized user to possess both the token and  the
        appropriate PIN.

             (iii)    In  addition   to  providing  identification   and
        authentication features in  its security  products, the  Company
        has included  in its  security systems  accounting and  auditing
        features that  allow customers  to track  and analyze  all  user
        access and  attempted access  to network  systems. This  permits
        easier  customer  implementation  and  monitoring  of  corporate
        security policies.

             (iv) The  Company  has  designed its  security  systems  to
        support various  platforms  _  such  as  Windows  NT  _  thereby
        allowing customers to ensure the same security for remote  users
        as is provided to office-based users.

             (v) The Company has sought to design products that are easy
        to use  and  competitively priced.  It  also is  increasing  its
        customer support capabilities to ensure the smooth  installation
        and maintenance of its systems.

        As a  result  of this  approach,  the Company  believes  it  has
   positioned itself to market a new generation of open  standards-based
   hardware and software security  systems, including those designed  to
   provide security to  Internet users, and  it intends  to continue  to
   grow to provide a full range of identification and authentication and
   other security products. See "The Company's Strategy" below.
<PAGE>
        Security   Token   Products.       Generally,   the    Company's
   challenge/response tokens work as  follows: when a  user logs onto  a
   computer or enters a program or network with a user ID, the  computer
   generates a numeric or alphanumeric  challenge and displays both  the
   challenge and a flashing bar pattern on the terminal screen. The user
   holds a token up to the flashing pattern on the screen, and the token
   reads and  interprets the  pattern and  then  displays a  unique,  or
   one-time, password  on  its liquid  crystal  display. The  user  then
   enters this password on the computer keyboard and, if a match exists,
   access to  the  computer,  program or  network  is  granted.  If  the
   terminal screen is not  able to display a  flashing bar pattern,  the
   user can enter the numeric or alphanumeric challenge into the  keypad
   on the token. PIN protected, break-in attempts to unlock the key  are
   tracked by the  token internally.  After a  pre-programmed number  of
   invalid attempts, the token  will be locked out  of the system for  a
   specified period of time.

        Some of the Company's products also are able to perform "digital
   signatures" for applications which  require proof that a  transaction
   was authorized. A  combination of  numbers from  the transaction  are
   entered into a  token which produces  an encrypted  number that  only
   that specific token, and the information from the transaction,  could
   have created. This number is then entered as part of the transaction,
   acting as a digital signature authorizing the transaction.

        The  Company's  security   tokens  include   AccessKey  II   and
   AuthentiCard, each an optical, hand-held challenge/response  security
   token with a liquid crystal display and numeric keypad that generates
   a  unique  password   each  time  it   is  used,   and  Digipass,   a
   time-synchronous  response  only  token  that  generates  a  one-time
   password, to authenticate  users of PCs  and networks  and to  verify
   data transmissions  by  electronic  signature.  In  early  1998,  the
   Company began full production and shipping of its Digipass 300, which
   is an  optical, hand-held  multiple-mode  security token  capable  of
   operating in time-synchronous  response only, challenge/response  and
   time synchronous challenge/response modes  and of performing  digital
   signature functions.

        Smartcards are also  emerging as viable  security devices.   The
   Company recently announced a new smartcard product, VACMan/CryptaPak,
   that  combines  two  authentication   standards  on  one   smartcard.
   VACMan/CryptaPak is a standards based smartcard solution that secures
   Internet applications based on the X.509 authentication standard  and
   also secures remote dial-in access based on the RADIUS authentication
   standard. It includes a smartcard, smartcard reader and software that
   enables  Netscape   Communications  Corporation's   Communicator   to
   authenticate users via  the X.509 certificate  standard and  software
   that enables remote dial-in users to be authenticated via the  RADIUS
   authentication standard. See "The Company's Security Products" below.
<PAGE>
        Encryption Products.  Hardware encryption product offerings from
   the Company include  DES and  RSA microprocessor  chips that  perform
   algorithmic functions  for  use in,  among  other things,  ATMs,  fax
   machines, modems and  security servers.   The Company's  DES and  RSA
   chips are also the central component  of its PC DES/RSA Cards,  which
   are printed  circuit  boards  that enable  software  applications  to
   provide encryption  security.    The  Company  also  has  acquired  a
   software encryption application, Point 'n  Crypt, which resides on  a
   PC workstation and  enables the user  to encrypt  or decrypt  Windows
   files or folders. See "The Company's Security Products" below.

        Access Control Products.  The  Company has, through a  strategic
   relationship, developed  the  VACMan  access  control  system,  which
   centralizes security services in a  single location, supports all  of
   the Company's  token  devices,  and is  based  on  industry  standard
   protocols to  maximize  interoperability.  VACMan  also  incorporates
   authorization and accounting  features. See  "The Company's  Security
   Products" below.

             (C)  The Company's Strategy

        The Company's  objective  is to  establish  itself as  a  single
   source data security solutions vendor and  to become a leader in  the
   data security market.  The Company's growth  is largely dependent  on
   the successful implementation of its business strategy. There can  be
   no assurance that the Company will be able to successfully  implement
   its business strategy or that, if implemented, such strategy will  be
   successful. See Subsection  d of Item  1 _ "Factors  That May  Affect
   Future Results" below.   Key elements of  the Company's strategy  for
   achieving this objective are listed below:

        Increase Name Recognition.  The Company intends to increase  the
   name recognition of  its products. It  believes that by  establishing
   itself as a brand name, it  will obtain a key competitive  advantage.
   The Company believes that  the market for  data security products  is
   confused by  multiple technologies  and conflicting  claims and  that
   end-users will  ultimately be  more comfortable  buying a  well-known
   product. The  Company intends  to increase  its name  recognition  by
   emphasizing sales  to  well-known visible  end-users,  expanding  its
   distribution network,  increasing its  presence at  technology  trade
   shows and other  increased marketing activities  such as print  media
   campaigns.

        Expand Product Line.  The Company  plans to continue to  broaden
   its line of  security products to  meet its customers'  needs and  to
   establish itself as  a single source  security solutions vendor.  The
   Company  intends  to  accomplish   this  by  continuing  to   develop
   identification and authentication  expertise, as well  as by  seeking
   strategic  relationships  and   acquiring  complementary  assets   or
   businesses.
<PAGE>
        Expand Global  Presence.   The implementation  of data  security
   products for electronic  banking in  the European  market has  become
   widespread and as a result, the market for the Company's products has
   grown more quickly  in Europe  than in  North America.  Sales by  the
   Company's European subsidiary,  VDS NV/SA, and  its U.S.  subsidiary,
   VDS, represented 77%  and 23%, respectively,  of the Company's  total
   revenue for the year ended December 31, 1997.  Nevertheless, sales to
   U.S. customers represented  just 8% of  the Company's  sales for  the
   year ended December 31,  1997.  The Company  believes that there  are
   significant opportunities for  its products in  the developing  North
   American market and further  believes it is  well positioned to  take
   advantage of this growing market. The Company intends to maintain and
   expand its  leadership role  in the  identification,  authentication,
   authorization and accounting  markets in Europe  and to leverage  its
   European  expertise   to   introduce  and   promote   the   Company's
   identification, authentication, authorization and accounting products
   to the  North American  and other  global markets.  Enterprises  that
   allow remote access to proprietary databases or information, or  need
   to  ensure  secure  data  transmission  for  purposes  of  electronic
   commerce (including via  the Internet), are  potential customers  for
   the Company's security products. The Company intends to pursue  these
   potential customers through its  growing network of distributors  and
   resellers. See "Expand Marketing Channels" below.

        Expand Marketing Channels.  The  Company intends to recruit  and
   support a network of value added resellers worldwide that  specialize
   in both vertical (banking, financial, health, telecommunications  and
   government)  markets  and  horizontal  (remote  access  and  Internet
   application) markets. By  undertaking these  activities, the  Company
   intends to address and fulfill the requirements of the growing remote
   access  market   that  is   in  need   of  advanced   identification,
   authentication, authorization and  accounting products.  Some of  the
   distributors and  resellers  that  have entered  into  agreements  to
   distribute  the  Company's  products  in  various  strategic  markets
   include:

<PAGE>
        Develop Strategic Relationships.   To  accomplish its  strategic
   goals, the  Company  has  established  and  is  developing  strategic
   relationships with other vendors  of complementary security  products
   and may seek to acquire complementary assets or businesses. Also, the
   Company has identified vendors of security or remote access  products
   that relied solely on static passwords that the Company believes  its
   products can enhance.

        The Company also has entered into co-development agreements with
   certain companies  to  gain  access to  technology  critical  to  the
   acceptance and adoption of the Company's technology and products. The
   first such agreement,  with TriNet  Services, Inc.,  resulted in  the
   Company's Internet  AccessKey, enabling  the  Company to  become  the
   first  security  authentication  vendor  to  enhance  security   when
   accessing the  Internet.   The Internet  AccessKey won  the 1996  Sun
   Microsystems Java Cup International award for productivity tools.

        The Company also  entered into a  co-development agreement  with
   SHIVA Corp.,  a leader  in  remote access  communications  equipment,
   pursuant to which  the Company licensed  from SHIVA  Corp. a  generic
   security server. The resulting product, VACMan, enables the Company's
   technology  and   products  to   be  inserted   into  virtually   any
   organization that  allows  remote  dial-in  access  to  its  computer
   networks.

        In addition,  the Company  entered  into an  original  equipment
   manufacturer  agreement  with  Netscape  Communications   Corporation
   ("Netscape") to  bundle Netscape  technology  and products  with  the
   Company's products. The first result is a new product - VACMan/LDAP -
   which allows installations to define user information, including  all
   token information, into Netscape's Directory Server. Netscape is  the
   first vendor  to  offer  a product  that  supports  a  newly  adopted
   worldwide standard  for directory  services. The  Company intends  to
   offer a  product  that  supports the  same  newly  adopted  worldwide
   standard for  directory services,  which will  result in  a  globally
   distributed security database accessible by a number of  applications
   requiring information about users.

              (D) The Company's Security Products

        The   Company's    family   of    hardware   products    include
   time-synchronous    response     only,     challenge/response     and
   time-synchronous challenge/response user authentication token devices
   or security tokens. Through December 31,  1997, the Company had  sold
   over 2.0  million  security tokens  (AccessKey II,  AuthentiCard  and
   Digipass 500). In  addition, the Company  recently began marketing  a
   smartcard security token  that uses the  challenge/response mode  and
   the X.509  certificate  authentication  standard.  The  Company  also
   designs, develops and markets encryption chips and encryption  boards
   through a  division called  Cryptech. The  primary customers  of  the
   Cryptech products  are  OEMs  of  telecommunications  equipment  that
   require real time encryption.
<PAGE>
        All the Company's  security tokens  are used  with its  software
   authentication server, VACMan, to provide a complete  identification,
   authentication, authorization and accounting security system.  VACMan
   supports each of the Company's security devices and permits users  to
   centralize their security systems  in a single  server or network  of
   servers. It is designed for small,  medium and large enterprises  and
   Internet  service  providers,  and  it  provides  a  centralized  and
   flexible solution for  managing network access.  VACMan is  scaleable
   for large  remote access  systems and  a  single server  can  support
   numerous distributed network access servers.

        The Company also offers  numerous additional products to  extend
   the  security   services  of   VACMan/Server  to   platforms   and/or
   applications that do not yet support the RADIUS protocol. Examples of
   such  products   are   VACMan/Client NT,   VACMan/Client   Enterprise
   (Netscape Web server), VACMan/Client IIS (Microsoft Web Server),  and
   VACMan/Client Solaris.  In addition  the Company  offers  workstation
   software to enhance network connections when using advanced  products
   like Digipass 300,  AuthentiCard, AccessKey  II or  VACMan/CryptaPak.
   These products  have unique  workstation requirements  to generate  a
   terminal flash pattern for the security tokens and to communicate  to
   a smartcard  reader  attached  to the  workstation  in  the  case  of
   VACMan/CryptaPak.

        The Company  also provides  a software  development kit  ("SDK")
   that can  be used  by other  vendors or  by clients  to build  RADIUS
   support into their products or applications. This SDK enables them to
   perform one  integration  project and  gain  support for  all  RADIUS
   compliant security servers. The SDKs are written in the C programming
   language and can  be used in  numerous operating system  environments
   such as MVS, VMS, UNIX, Windows, NetWare and DOS. The SDKs enable the
   Company's strategic partners to integrate the Company's products into
   their own product offerings.

   States.  In  addition,  AuthentiCard  and  Digipass  are   trademarks
   registered in Belgium.
<PAGE>
        (iv) Intellectual Property and Proprietary Rights

        The Company  relies  on  a  combination  of  patent,  copyright,
   trademark and trade secret laws, as well as employee and  third-party
   non-disclosure agreements  to  protect  its  proprietary  rights.  In
   particular, the Company  holds several patents  in the United  States
   and a corresponding patent in certain European countries, which cover
   certain aspects of its technology. The majority of its patents  cover
   the  Company's  AccessKey   II,  Digipass  500,   Digipass  300   and
   AuthentiCard tokens.  The U.S.  patents expire  between 2003  through
   2010; the European patent expires in 2008. The Company believes these
   patents to be valuable property rights and relies on the strength  of
   its patents and trade secret law to protect its intellectual property
   rights. To the extent that the Company believes its patents are being
   infringed upon, it intends to assert vigorously its patent protection
   rights, including but  not limited to,  pursuing all available  legal
   remedies.

        While the Company believes that its patents are material to  its
   future success, there can be no assurance that the Company's  present
   or future patents, if any, will  provide a competitive advantage.  It
   also may be possible for others  to develop products with similar  or
   improved functionality  that will  not  infringe upon  the  Company's
   intellectual property  rights. Furthermore,  to the  extent that  the
   Company believes that its proprietary rights are being violated,  and
   regardless of its desire to do so, it may not have adequate financial
   resources to engage in  litigation against the  party or parties  who
   may infringe on its proprietary technology. See Subsection d of  Item
   1 _ "Factors That May Affect Future Results _ Proprietary  Technology
   and Intellectual Property."

        (v)  Research and Development

        The Company's  research  and  development  ("R&D")  efforts  are
   concentrated on product enhancement,  new technology development  and
   related new  product  introductions. As  of  December 31,  1997,  the
   Company employed  13  full-time engineers  and,  from time  to  time,
   independent engineering firms to conduct non-strategic R&D efforts on
   its behalf. For the fiscal years  ended December 31, 1995, 1996   and
   1997,  the  Company  expended  $242,000,  $575,000  and   $1,802,000,
   respectively, on R&D,  representing approximately 7%,  6% and 15%  of
   the  Company's  consolidated  revenues  for  1995,  1996  and   1997,
   respectively. See Item 7 _  "Management's Discussion and Analysis  of
   Financial Condition and Results of Operations."
        While management is committed  to enhancing its current  product
   offerings, and introducing  new products, there  can be no  assurance
   that the Company's R&D activities will be successful in this  regard.
   Furthermore, there can be no assurance that the Company will have the
   financial resources required to identify and develop new technologies
   and to bring new  products to market in  a timely and cost  effective
   manner, or that any such products will be commercially successful  if
   and when they are introduced.
<PAGE>
        (vi) Production

        The Company's  security hardware  products are  manufactured  by
   third parties pursuant to purchase orders issued by the Company.  Its
   hardware products are comprised  primarily of commercially  available
   electronic components  which are  purchased globally.  The  Company's
   software products are  controlled in-house by  Company personnel  and
   can be  produced either  in-house or  by several  outside sources  in
   North America and in Europe.

        With the  exception of  the  AccessKey II token,  the  Company's
   security   tokens   utilize   commercially   available   programmable
   microprocessors, or chips. The Company uses two microprocessors, made
   by Samsung  and Epson,  for the  various hardware  products  produced
   other than the  AccessKey II token. The  Samsung microprocessors  are
   purchased from  Samsung  Semiconductor  in  Belgium,  and  the  Epson
   microprocessors are  purchased  from Alcom  Electronics  NV/SA,  also
   located in Belgium.  The microprocessors are  the only components  of
   the Company's security  tokens that are  not commodity items  readily
   available on  the  open  market. While  there  is  an  inherent  risk
   associated  with  each  supplier  of  microprocessors,  the   Company
   believes having two sources reduces the overall risk.

        AccessKey   II   uses    a   custom-designed   and    fabricated
   microprocessor which  is currently  available from  a single  source,
   Micronix Integrated Systems, in the  United States. The Company  does
   not have  a  long-term contract  with  Micronix, but  rather  submits
   blanket purchase  orders for  the  AccessKey II  microprocessor.  The
   Company expects AccessKey II production to be reduced during 1998  as
   the production  of Digipass  300, which  employs a  widely  available
   microprocessor, increases.   Due  to the  use of  a widely  available
   microprocessor in the Digipass 300, the risks associated with  vendor
   selection and lead times should be reduced.

        Orders of microprocessors  and some  other components  generally
   require a lead time of 12-16 weeks. The Company attempts to  maintain
   a sufficient inventory of  all parts to handle  short term spikes  in
   orders. Large orders that  would significantly deplete the  Company's
   inventory are typically required to be placed with more than 12 weeks
   of lead time,  allowing the Company  to attempt  to make  appropriate
   arrangements with its suppliers.

        The Company purchases the majority of its product components and
   arranges for shipment to  third parties for  assembly and testing  in
   accordance with design specifications.  The Company's three  security
   token  products  are   assembled  exclusively   by  two   independent
   companies, each of which is based in Hong Kong. Purchases from one of
   the companies are made on a  purchase order by purchase order  basis.
   Purchases from the other company are under a contract that extends to
   January 21,  1999,  with  automatic  one-year  renewals,  subject  to
   termination on six month's notice. Each of these companies  assembles
   the Company's security tokens at facilities in mainland China. One of
   the companies  also maintains  manufacturing capacity  in Hong  Kong.
   Equipment designed  to test  products at  the  point of  assembly  is
   supplied by  the Company  and periodic  visits  are made  by  Company
   personnel for purposes of quality assurance, assembly process  review
   and supplier relations.
<PAGE>
        There can be no assurance that  the Company will not  experience
   interruptions in the supply of either of the component parts that are
   used in its products or fully-assembled token devices in general.  In
   the event  that  the flow  of  components or  finished  products  was
   interrupted, there could be a considerable delay in finding  suitable
   replacement sources for those components,  as well as in  replacement
   assembly subcontractors with the  result that the Company's  business
   and results of operations could be adversely affected. See Subsection
   d of Item 1 _ "Factors That May Affect Future Results _ Dependence on
   Single Source Suppliers."

        (vii)     Competition

        The market for computer and  network security solutions is  very
   competitive and, like most  technology-driven markets, is subject  to
   rapid change  and  constantly  evolving products  and  services.  The
   industry is comprised of  many companies offering hardware,  software
   and  services   that  range   from  simple   locking  mechanisms   to
   sophisticated encryption  technologies.  The  Company  believes  that
   competition in this  market is  likely to  intensify as  a result  of
   increasing demand for  security products.  The Company's  competition
   comes from  a number  of  sources, including  (i) software  operating
   systems suppliers and application software vendors that incorporate a
   single-factor static password  security system  into their  products,
   and (ii) token-based  password generator  vendors promoting  response
   only and/or challenge/response technology,  such as ActivCard,  Inc.,
   AXENT Technologies, Inc., CRYPTOCard,  Inc., Leemah DataCom  Security
   Corporation,  Racal-Guardata,  Inc.,  Secure  Computing  Corp.,   and
   Security Dynamics Technologies, Inc.

        In some cases, these vendors also support the Company's products
   and those of its competitors. The  Company also may face  competition
   in the future from these and other parties in the future that develop
   computer and network security products based upon approaches  similar
   to or different from those employed  by the Company. There can be  no
   assurance that the market for computer and network security  products
   will not  ultimately  be  dominated  by  approaches  other  than  the
   approach marketed by the Company.

        The Company  believes  that the  principal  competitive  factors
   affecting the  market  for  computer and  network  security  products
   include  name   recognition,  technical   features,  ease   of   use,
   quality/reliability, level of security, customer service and support,
   distribution channels and price.  Although the Company believes  that
   its  products  currently  compete  favorably  with  respect  to  such
   factors, other than name recognition in certain markets, there can be
   no assurance that the Company  can maintain its competitive  position
   against current  and  potential competitors,  especially  those  with
   significantly  greater   financial,  marketing,   service,   support,
   technical and other competitive resources.
<PAGE>
        Many of  the Company's  present and  potential competitors  have
   significantly  greater   financial,  marketing,   service,   support,
   technical and other competitive resources than the Company and, as  a
   result, may  be able  to  respond more  quickly  to new  or  emerging
   technologies and  changes  in  customer requirements,  or  to  devote
   greater resources to the development, promotion and sale of products,
   or to deliver competitive products at a lower end-user price. Current
   and  potential  competitors   have  established   or  may   establish
   cooperative relationships among themselves  or with third parties  to
   increase the ability of  their products to address  the needs of  the
   Company's prospective customers. Accordingly, it is possible that new
   competitors or alliances may  emerge and rapidly acquire  significant
   market share.  If this  were to  occur,  the financial  condition  or
   results of operations  of the Company  could be materially  adversely
   effected. See  Subsection d  of Item 1  _  "Factors That  May  Affect
   Future Results _ Competition."

        The Company's products  are designed to  allow authorized  users
   access to  a  computing environment,  in  some cases  using  patented
   technology as a replacement for the static password. Although certain
   of the Company's security token technologies are patented, there  are
   other  organizations  that   offer  token-type  password   generators
   incorporating challenge/response  or  response only  approaches  that
   employ different technological solutions and compete with the Company
   for market share.

        (viii)    Sales and Marketing

        The  Company's  computer  and  network  security  products   are
   marketed primarily through an indirect sales channel and distribution
   network and, to a lesser extent,  directly to end-users. The  Company
   markets its products primarily in North America and Europe through  a
   combination   of    value-added   resellers,    original    equipment
   manufacturers, independent distributors and  direct sales efforts.  A
   sales staff of 12 (as of December 31, 1997) coordinates sales through
   the distribution network and makes direct sales calls either alone or
   with sales personnel of vendors of computer systems. The sales  staff
   also provides  product  education  seminars  to  sales  personnel  of
   vendors and distributors with whom the Company has working  relations
   and to potential end-users of the Company's products.

        In January 1997,  the VASCO Advantage  Reseller ("VAR")  program
   was introduced. The goal of this  program is to expand the  Company's
   marketing  channels  by  engaging  companies  already  proficient  in
   reselling  computer  network  products  and  security  solutions   to
   distribute the Company's products.
<PAGE>
        The Company works with these resellers through its United States
   and European operating subsidiaries, VDS and VDS NV/SA. VDS, which is
   primarily responsible  for North  America, South  America and  Japan,
   started  in  1997   with  one  reseller.   Since  January  1,   1997,
   arrangements have been made with 39 additional resellers, for a total
   of 40  as  of  December  31, 1997.  VDS  NV/SA,  which  is  generally
   responsible for developing sales in the  remainder of the world,  had
   an existing base of 17 resellers prior to the announcement of the VAR
   program.    Between  January  1,  1997  through  December  31,  1997,
   VDS NV/SA engaged  an additional  20 resellers,  for a  total  of 37.
   Combined, VDS and VDS NV/SA established relationships with a total of
   77 resellers in 1997, against a target of 64.  As of March 31,  1998,
   VDS NV/SA's resellers numbered 40 and  VDS' numbered 46, for a  total
   of 86.

        The Company's international sales and operations are subject  to
   risks such as the imposition of  government controls, new or  changed
   export license requirements, restrictions  on the export of  critical
   technology, trade  restrictions and  changes  in tariffs.  While  the
   Company believes its  products are  designed to  meet the  regulatory
   standards  of  foreign  markets,  any  inability  to  obtain  foreign
   regulatory approvals on a timely basis could have a material  adverse
   effect on the Company's financial condition or results of operations.

        The Company's products  are subject to  export restrictions  and
   controls  as  administered  by  the  National  Security  Agency,  the
   Department of  State  and  the  Department  of  Commerce.  Encryption
   products  are  eligible  for  export  depending  upon  the  level  of
   encryption technology incorporated into the product. U.S. export laws
   also prohibit the export of encryption products to specified  hostile
   countries. Until recently, the  Company did not  need to obtain  U.S.
   export  licenses  for  its  products.  However,  two  new  encryption
   products, VACMan/CryptaPak and VACMan/Point  `n Crypt, introduced  to
   the product line in August 1997,  require a License Exception  (i.e.,
   authorization to export, under  stated conditions, subject to  Export
   Administration Regulations). The Company believes it will be able  to
   obtain  License  Exceptions   for  both   its  VACMan/CryptaPak   and
   VACMan/Point `n Crypt products for sales to international banking and
   financial institutions.

        There can be no  assurance, however, that  the list of  products
   and  countries  for  which  export  approval  is  required,  and  the
   regulatory policies with  respect thereto  will not  be revised  from
   time to  time.  The  inability of  the  Company  to  obtain  required
   approvals under these regulations  could materially adversely  affect
   the ability  of  the  Company to  make  international  sales  of  the
   products under U.S. export control.

        The  Company's  core  authentication  products,  AccessKey   II,
   Digipass 300, Digipass 500,  and AuthentiCard, do  not, nor are  they
   likely to,  fall under  U.S. encryption  export control  regulations.
   Although  all  of  the  Company's  authentication  products   utilize
   encryption technologies, the products cannot read and encrypt  client
   data. Thus,  they  are not  subject  to the  U.S.  encryption  export
   control regulations.
<PAGE>
        Similarly, VDS NV/SA is subject to export licensing requirements
   under  Belgian  law.  VDS  NV/SA,  as  owner  and  exporter  of   the
   cryptographic  products,  must  apply  to  the  Belgian  Ministry  of
   Economic Affairs for an export license  for each company to which  it
   exports such products. An  export license is  valid for one  customer
   for one year from  the date of  issue. It can  be reused for  several
   consecutive deliveries  to  that  customer  until  the  total  export
   quantity indicated on the license has been exhausted. If the quantity
   is not completely exported  during the one  year license period,  the
   license can be renewed once for  another year. VDS NV/SA applies  for
   such licenses  for  customers  that wish  to  purchase  cryptographic
   products. The inability of VDS NV/SA to obtain required approvals  or
   licenses under Belgian law  could have a  material adverse effect  on
   the Company's financial condition or operations.

        The  Belgian  export  of  VDS  NV/SA's  cryptographic  products,
   consisting of DES and  RSA microprocessors and  PC/DES and RSA  cards
   (including SDKs), is also subject to European Community  regulations.
   VDS NV/SA's cryptographic  products are  considered to  be "goods  of
   dual use" under those regulations, i.e.,  goods that can be used  for
   both civil  and military  purposes. As  such, a  national  individual
   export license is required for their export, except to Luxembourg and
   the Netherlands. Only the VDS NV/SA products that perform  encryption
   of data  for confidentiality  reasons  require an  individual  export
   license, and VDS NV/SA has obtained  such licenses for the export  of
   these products.

        (ix) Customers and Markets

        Customers for the Company's  security products include, to  some
   extent, businesses that purchase  products directly from the  Company
   for use by their employees, clients or vendors, but the majority  are
   value-added resellers or distributors of related security products or
   services who in turn sell to other businesses.

        To date, virtually all of  the Company's security products  have
   been  sold   in   Europe.   Sales  to   one   European   distributor,
   Concord-Eracom Nederland  BV,  accounted  for  44%  and  16%  of  the
   Company's consolidated revenues in 1996 and 1997, respectively. On  a
   pro forma basis (i.e., including  Lintel Security and Digipass  sales
   for all of 1996)  this customer would have  accounted for 33% of  the
   Company's consolidated revenues  for 1996. This  drop is  due to  the
   reduction in shipments  to Concord-Eracom Nederland  BV during  1997,
   resulting in revenues from such shipments dropping to $2 million from
   $4 million in 1996.   In 1998,  however, Concord-Eracom Nederland  BV
   placed an additional $1.25 million order with VASCO NA. For 1996,  on
   a pro forma basis, Rabobank and S-E Banken each would have  accounted
   for approximately 10%  of the Company's  total revenues.   For  1997,
   these two  customers  each accounted  for  approximately 18%  of  the
   Company's total  revenues. For  additional information,  see Item  7_
   "Management's Discussion  and  Analysis of  Financial  Condition  and
   Results of Operations _ 1997 Compared to 1996 _ Revenues."
<PAGE>
        The Company is aware of the risks associated with this degree of
   customer concentration and expects  to further minimize its  reliance
   on these customers  in 1998 and  beyond. There can  be no  assurance,
   however, that  the  Company's  efforts to  minimize  this  risk  will
   ultimately be successful or that  the Company can sustain  comparable
   sales volume with  these customers.  Furthermore, the  loss of  these
   customers' business, or  an inability to  maintain reasonable  profit
   margins on these sales,  may have an adverse  effect on the  Company.
   See Subsection d of Item 1 _ "Factors That May Affect Future  Results
   _ Dependence  on  Major  Customers" and  "_  Risks  of  International
   Operations."

         (x) Backlog

        At March 31,  1998, the Company  had firm  purchase orders  from
   customers  for   an   aggregate  of   $7,066,000   of   AccessKey II,
   AuthentiCard, Digipass  500 and  Digipass 300  security token  units,
   exclusive of the units already shipped under such purchase orders  as
   of March 31, 1998.   This compares to a  balance of $3,700,000 as  of
   March 31, 1997.

        (xi) Employees

        As of  December  31, 1997,  the  Company employed  40  full-time
   employees and 6 full-time consultants. Of  these, 22 were located  in
   North America and 24 were located in Europe. Of the 46 total, 15 were
   involved in  sales, marketing  and customer  support, 17  in  product
   production, research and development and 14 in administration.

   d.   Factors That May Affect Future Results

        (i)  History of Operating Losses; Accumulated Deficit

        The Company  has  incurred  losses  from  continuing  operations
   before interest and taxes for the years ended December 31, 1995, 1996
   and 1997 of $534,000, $8,658,000 and $3,935,000, respectively. As  of
   December  31,  1997,  the  Company  had  an  accumulated  deficit  of
   $15,902,000, which amount includes write-offs of acquired  in-process
   technology  related  to  the  acquisitions  of  Lintel  Security  and
   Digipass for  the year  ended  December 31,  1996  in the  amount  of
   $7,351,000. See Item  7 _  "Management's Discussion  and Analysis  of
   Financial Condition  and Results  of Operations."    In view  of  the
   Company's history  of losses,  there can  be  no assurance  that  the
   Company will be able to achieve or sustain profitability on an annual
   or quarterly basis in the future.
<PAGE>
        (ii) Potential Fluctuations in Quarterly Results

        The Company's  quarterly  operating  results have  in  the  past
   varied and may  in the future  vary significantly. Factors  affecting
   operating results  include:  the  level  of  competition;  the  size,
   timing, cancellation or  rescheduling of  significant orders;  market
   acceptance of  new products  and  product enhancements;  new  product
   announcements or introductions by the Company's competitors; adoption
   of new technologies and standards; changes in pricing by the  Company
   or its competitors; the ability of the Company to develop,  introduce
   and market new products and product  enhancements on a timely  basis,
   if at all; component costs and availability; the Company's success in
   expanding its sales and marketing programs; technological changes  in
   the market  for data  security  products; foreign  currency  exchange
   rates; and general  economic trends and  other factors. In  addition,
   because a high  percentage of  the Company's  operating expenses  are
   fixed, a small variation in the timing of recognition of revenue  can
   cause significant  variations in  operating results  from quarter  to
   quarter.

        (iii)     Additional Capital Needed

        The Company requires additional  capital to finance its  working
   capital and  other  needs,  including the  repayment  of  outstanding
   obligations and the financing of future growth. The Company  believes
   its  current  cash  balances  and  anticipated  cash  revenues   from
   operations will  be sufficient  to meet  its anticipated  cash  needs
   through December 31, 1998.

        Continuance of  the  Company's operations  beyond  December  31,
   1998, however,  will  depend  on  the  Company's  ability  to  obtain
   adequate financing. To this end, in  April 1998, the Company  entered
   into a loan  agreement in  the amount of  $3 million  with Lernout  &
   Hauspie Speech  Products  N.V.  ("L&H"); the  funding  of  this  loan
   occurred during April 1998. The loan bears interest at the Prime Rate
   plus 1%, payable quarterly, and matures on January 4, 1999. L&H is an
   international leader in the development of advanced speech technology
   for  various  commercial  applications  and  products.  Although  the
   Company has obtained the necessary financing in the past and  intends
   to raise capital in  the near future  through, among other  potential
   financing sources, a possible public offering of Common Stock,  there
   is no assurance that it will be able to do so in the future. Further,
   there is no assurance that the Company can reduce its expenditures or
   sell assets or proprietary rights without having a material effect on
   its business.  See Item 7 _ "Management's Discussion and Analysis  of
   Financial Condition and Results of Operations _ Liquidity and Capital
   Resources."
<PAGE>
         (iv)     Rapid Technological  Changes  and  Dependence  on  New
   Products

        The market  for  the  Company's products  is  very  dynamic  and
   characterized  by  rapidly  changing  technology,  evolving  industry
   standards and  government policies,  changing customer  requirements,
   price-competitive  bidding  and  frequent  product  enhancements  and
   innovations. The introduction  by the Company  or its competitors  of
   products embodying new technologies and the emergence of new industry
   standards could render the  Company's existing products obsolete  and
   unmarketable. Therefore, the Company's future success will depend  in
   part upon its  ability to enhance  its current  products and  develop
   innovative products to distinguish itself from the competition and to
   meet customers' changing needs in the data security industry.

        The Company  is  presently expending  significant  resources  to
   enhance its  existing products  and develop  and introduce  the  next
   generation of  token and  other security  products. There  can be  no
   assurance that security-related  product developments and  technology
   innovations  by  others  will  not  adversely  affect  the  Company's
   competitive position or that the Company will be able to successfully
   anticipate or  adapt to  changing technology,  industry standards  or
   customer requirements on a timely basis.  Any failure by the  Company
   to anticipate  and respond  to such  changes  could have  a  material
   adverse effect on the Company's  results of operations and  financial
   condition.

        (v)  Dependence on Major Customers

        Approximately 16%  of the  Company's revenues  during 1997  were
   derived from  the sale  of the  Company's  security products  to  one
   European distributor, Concord-Eracom Nederland BV. For 1996, on a pro
   forma basis, Rabobank and  S-E Banken each  would have accounted  for
   approximately 10% of the Company's total  revenues.  For 1997,  these
   two customers each accounted for  approximately 18% of the  Company's
   total revenues. There can  be no assurance that  the Company will  be
   able to modify  its existing products  or develop  new products  that
   will continue to meet the  specifications of these customers.  Absent
   significant future revenues from alternative sources, the  unforeseen
   loss of one or  more of the Company's  major customers' business,  or
   the inability to maintain reasonable profit  margins on sales to  any
   of these  customers, would  have a  material  adverse effect  on  the
   Company's results of operations and financial condition. See Item 7 _
   "Management's Discussion  and  Analysis of  Financial  Condition  and
   Results of Operations"  and Item  1, Subsection  c.(ix) _  "Narrative
   Description of Business - Customers and Markets."

        (vi) Product Concentration

        Sales of the Company's AccessKey II and Digipass security tokens
   together comprised the  majority of  the Company's  net sales  during
   fiscal 1995,  1996 and  1997. Should  the demand  for or  pricing  of
   either of these products decline due to the introduction of  superior
   or lower  cost  products  by competitors,  changes  in  the  computer
   industry or other  factors, the Company's  results of operations  and
   financial condition would be adversely affected.
<PAGE>
        (vii)     Dependence on Development of Industry Relationships

        The Company is party to collaborative arrangements with a number
   of  corporations  and  evaluates,  on  an  ongoing  basis,  potential
   strategic  alliances  and   intends  to  continue   to  pursue   such
   relationships. The Company's future success will depend significantly
   on the  success  of  its current  arrangements  and  its  ability  to
   establish additional  arrangements. There  can be  no assurance  that
   these arrangements will result  in commercially successful  products.
   See  Item  1,  Subsection  c.(iii)(C)  _  "Narrative  Description  of
   Business _ Products  _ The Company's  Strategy   _ Develop  Strategic
   Relationships."

        (viii)    Risks of International Operations
        Sales to  customers  outside  the United  States  accounted  for
   approximately 61%, 95% and 92% of  the Company's net revenues in  the
   years ended December 31, 1995, 1996 and 1997, respectively. Because a
   significant number of the  Company's principal customers are  located
   in other countries, management expects that international sales  will
   continue to generate  a significant  portion of  the Company's  total
   revenue.

        The Company's international business is subject to a variety  of
   risks, including tariffs and other trade barriers, the  establishment
   and expansion of indirect distribution channels in certain  countries
   or  regions,  delays  in  expanding  its  international  distribution
   channels, difficulties collecting  international accounts  receivable
   from distributors  or  resellers,  increased  costs  associated  with
   maintaining international  marketing  efforts,  the  introduction  of
   non-tariff  barriers  and  difficulties  in  enforcing   intellectual
   property rights.

        In addition, the majority of  the supply and sales  transactions
   of VDS are denominated  in U.S. dollars, whereas  many of the  supply
   and sales  transactions  of  VDS NV/SA  are  denominated  in  various
   foreign currencies. A decrease in the  value of any of these  foreign
   currencies relative to the U.S. dollar could affect the profitability
   in U.S. dollars of the Company's products sold in these markets.  The
   Company  is   therefore  subject   to  the   risks  associated   with
   fluctuations in currency exchange rates.

        In order to reduce the risk of fluctuations in currency exchange
   rates, VDS NV/SA began in 1997 to buy U.S. dollars based on three- to
   six-month estimated  future needs  for  U.S. dollars,  has  developed
   price lists denominated in both U.S. dollars and foreign  currencies,
   and endeavors to denominate its new supply and sales transactions  in
   U.S. dollars.  In  this  connection,  in  September  1997  VDS  NV/SA
   purchased $300,000 in  U.S. dollars to  cover purchases of  supplies.
   VDS NV/SA  is also  beginning to  attempt to  match as  to timing  of
   delivery, amount  of  product  and  denomination  of  currency,  some
   purchase orders from  vendors with sales  orders to customers.  There
   can be no assurance that these matching efforts will be successful in
   reducing currency exchange risks or  that the risks of  international
   operations will not have a material  adverse effect on the  Company's
   financial condition or results of operations.
<PAGE>
        The Company does  not hold forward  exchange contracts or  other
   hedging instruments to exchange  various foreign currencies for  U.S.
   dollars to offset currency rate  fluctuations which might affect  its
   obligations in relation  to its repayment  out of  income from  sales
   (which are principally in  foreign currency) of  debt under its  loan
   obligations (which are  principally in U.S.  dollars). See  Item 7  _
   "Management's Discussion  and  Analysis of  Financial  Condition  and
   Results of Operations."

        (ix) Competition

        The market for computer and network security products is  highly
   competitive and subject  to rapid change.  The Company believes  that
   the principal competitive factors  affecting the market for  computer
   and network  security products  include name  recognition,  technical
   features,  ease  of  use,  quality/reliability,  level  of  security,
   customer service and  support, distribution channels  and price.  The
   Company's competitors include organizations that provide computer and
   network security  products  based  upon  approaches  similar  to  and
   different from  those  employed  by the  Company.  There  can  be  no
   assurance that the market for computer and network security  products
   will not  ultimately  be  dominated  by  approaches  other  than  the
   approach marketed by the Company.   See Item 1, Subsection c.(ii)   _
   "Narrative  Description  of  Business  _  Industry  Background"   and
   Subsection  c.(vii)   _   "Narrative  Description   of   Business   _
   Competition."

        Many of the Company's  potential competitors have  significantly
   greater  financial,  marketing,   technical  and  other   competitive
   resources than the Company.  As a result, they  may be able to  adapt
   more quickly to new or emerging technologies and changes in  customer
   requirements, or to  devote greater  resources to  the promotion  and
   sale of  their  products  than can  the  Company.  Competition  could
   increase if new companies enter the market or if existing competitors
   expand their product lines. Any reduction in gross margins  resulting
   from competitive factors could have a material adverse effect on  the
   Company's financial condition or results of operations.

        Although the Company believes  it has certain technological  and
   other advantages over  its competitors,  maintaining such  advantages
   will require  continued investment  by the  Company in  research  and
   development and sales and marketing. There  can be no assurance  that
   the Company will have sufficient  resources to make such  investments
   or that the Company will be  able to make the technological  advances
   necessary to  maintain  such  competitive  advantages.  In  addition,
   current and  potential competitors  have established  or may  in  the
   future establish collaborative relationships among themselves or with
   third parties,  including third  parties with  whom the  Company  has
   strategic relationships, to increase the ability of their products to
   address the security  needs of the  Company's prospective  customers.
   Accordingly, it is  possible that  new competitors  or alliances  may
   emerge and rapidly acquire significant market share. If this were  to
   occur, the  financial  condition and  results  of operations  of  the
   Company  would  be  materially   adversely  affected.  See  Item   1,
   Subsection  c.(vii)   _   "Narrative  Description   of   Business   _
   Competition."
<PAGE>
        (x)  Dependence on Single Source Suppliers

        The majority of the Company's  products are manufactured by  two
   independent vendors headquartered in Hong Kong. One of the vendors is
   under a contract  that extends to  January 21,  1999, with  automatic
   one-year renewals subject  to termination  on six  months notice  and
   purchases from the other vendor are  on a purchase order by  purchase
   order basis. Each vendor assembles  the Company's security tokens  at
   facilities in mainland China. The importation of these products  from
   China exposes  the  Company  to the  possibility  of  product  supply
   disruption and  increased  costs  in the  event  of  changes  in  the
   policies of  the Chinese  government,  political unrest  or  unstable
   economic conditions in  China or  developments in  the United  States
   that are  adverse  to  trade, including  enactment  of  protectionist
   legislation. While the Company believes that it could find substitute
   contractors for the manufacture and assembly of its products, and has
   had discussions to that effect with a vendor in Belgium, in the event
   that the supply of components or finished products is interrupted  or
   relations with either  of the  two principal  vendors is  terminated,
   there could  be a  considerable  delay finding  suitable  replacement
   sources to  manufacture the  Company's products  which could  have  a
   material adverse effect  on the Company's  results of operations  and
   financial condition. In addition, the Company's AccessKey II  product
   contains a custom-designed  microprocessor which is  fabricated by  a
   single supplier  located in  the United  States  and is  procured  by
   purchase orders. The  Company expects AccessKey  II production to  be
   reduced during 1998 as the production of Digipass 300, which  employs
   a widely available microprocessor, increases. However, any unforeseen
   interruption in the  supply of microprocessors  for the AccessKey  II
   from the sole supplier prior to the full phase-in of the Digipass 300
   product would have a material adverse effect on the Company's results
   of operations and financial condition. See Item 1, Subsection  c.(vi)
   _ "Narrative Description of Business _ Production."

        (xi) Proprietary Technology and Intellectual Property

        The Company's success depends significantly upon its proprietary
   technology. The Company currently relies on a combination of  patent,
   copyright  and   trademark  laws,   trade  secrets,   confidentiality
   agreements and  contractual  provisions to  protect  its  proprietary
   rights. The Company seeks to protect its software, documentation  and
   other written materials under trade secret and copyright laws,  which
   afford only  limited protection.  The Company  generally enters  into
   confidentiality and nondisclosure agreements  with its employees  and
   with key vendors and suppliers. The Company holds several patents  in
   the United  States and  a corresponding  patent in  certain  European
   countries, which cover  certain aspects of  its technology. The  U.S.
   patents expire between 2003 through 2010; the European patent expires
   in 2008. There  can be  no assurance  that the  Company will  develop
   proprietary products or  technologies that are  patentable, that  any
   issued  patent  will  provide   the  Company  with  any   competitive
   advantages or  will  not be  challenged  by third  parties,  or  that
   patents of others  will not  have a  material adverse  effect on  the
   Company's business.
<PAGE>
        There has  also been  substantial litigation  in the  technology
   industry regarding intellectual property  rights, and litigation  may
   be necessary  to protect  the Company's  proprietary technology.  The
   Company expects  that  companies  in  the  computer  and  information
   security market will increasingly  be subject to infringement  claims
   as the number  of products and  competitors in  the Company's  target
   market grows. Any such claims or litigation may be time-consuming and
   costly,  cause  product  shipment  delays,  require  the  Company  to
   redesign its products or require the Company to enter into royalty or
   licensing agreements,  any of  which could  have a  material  adverse
   effect  on  the  Company's   results  of  operations  and   financial
   condition.

        Despite the Company's efforts to protect its proprietary rights,
   unauthorized parties may  attempt to  copy aspects  of the  Company's
   products or  to obtain  and use  information  and software  that  the
   Company regards as  proprietary. To the  extent the Company  believes
   its proprietary  rights are  being violated,  and regardless  of  its
   desire to do  so, it  may not  have adequate  financial resources  to
   engage in litigation against the party or parties who may infringe on
   its proprietary technology.  In addition,  the laws  of some  foreign
   countries do not protect proprietary and intellectual property rights
   to as great an extent as do the laws of the United States. There  can
   be  no  assurance  that  the   Company's  means  of  protecting   its
   proprietary and intellectual property rights will be adequate or that
   the Company's  competitors  will not  independently  develop  similar
   technology, duplicate the Company's products or design around patents
   issued to the Company  or other intellectual  property rights of  the
   Company.

        (xii)     Product Liability Risks

        Customers rely on the Company's token-based security products to
   prevent unauthorized access to their data. A malfunction of or design
   defect in the  Company's products could  result in  tort or  warranty
   claims. The  Company does  not presently  maintain product  liability
   insurance for these types of claims.  In order to reduce the risk  of
   exposure from such  claims, the Company  attempts to obtain  warranty
   disclaimers and liability limitation  clauses in its agreements  with
   distributors, resellers and end-user  clients. However, there can  be
   no assurance that the  Company will be  successful in obtaining  such
   provisions in its agreements or that such measures will be  effective
   in limiting  the  Company's  liability  for  any  such  damages.  Any
   liability for  damages  resulting  from security  breaches  could  be
   substantial and would have a material adverse effect on the Company's
   results  of  operations  and  financial  condition.  In  addition,  a
   well-publicized  actual  or   perceived  security  breach   involving
   token-based security  systems  could adversely  affect  the  market's
   perception of  token-based  security  products  in  general,  or  the
   Company's products in particular,  regardless of whether such  breach
   is attributable to  the Company's products.  This could  result in  a
   decline in  demand for  the Company's  products, which  would have  a
   material adverse effect  on the Company's  results of operations  and
   financial condition.
<PAGE>
        (xiii)    Government Regulation of Technology Exports

        The Company's international sales and operations are subject  to
   risks such as the imposition of  government controls, new or  changed
   export license requirements, restrictions  on the export of  critical
   technology, trade  restrictions and  changes  in tariffs.  While  the
   Company believes its  products are  designed to  meet the  regulatory
   standards  of  foreign  markets,  any  inability  to  obtain  foreign
   regulatory approvals on a timely basis could have a material  adverse
   effect on the Company's financial condition or results of operations.

        Certain products of the Company  are subject to export  controls
   under U.S. law,  and the  Company believes  it has  obtained or  will
   obtain all necessary export  approvals as required.  There can be  no
   assurance, however, that the list of products and countries for which
   export approval is required, and the regulatory policies with respect
   thereto will not be revised from  time to time. The inability of  the
   Company to obtain  required approvals under  these regulations  could
   materially adversely  affect  the  ability of  the  Company  to  make
   international sales. For example,  U.S. governmental controls on  the
   exportation  of  encryption  technology  prohibit  the  Company  from
   exporting some  of  its products  with  the more  sophisticated  data
   security encryption  technology.  As a  result,  foreign  competitors
   facing  less  stringent  controls  may   be  able  to  compete   more
   effectively than  the Company  in the  global data  security  market.
   There can be no assurance that these factors will not have a material
   adverse effect on  the Company's  financial condition  or results  of
   operations.

        Similarly, VDS NV/SA,  the Belgian operating  subsidiary of  the
   Company, is subject  to export licensing  requirements under  Belgian
   law. The  inability of  VDS NV/SA  to  obtain required  approvals  or
   licenses under Belgian law also could have a material adverse  effect
   on the Company's  financial condition or  results of operations.  For
   additional information  on  such export  restrictions  and  licensing
   requirements under  U.S.  and Belgian  law,  see Item  1,  Subsection
   c.(viii) _ "Narrative Description of Business _ Sales and Marketing."

        (xiv)     Dependence on Key Personnel

        The Company depends, to a significant  degree on the efforts  of
   its President, Chief Executive Officer and the Chairman of its  Board
   of Directors,  T. Kendall  Hunt, and  those  of other  key  personnel
   employed by or serving as consultants to its subsidiaries,  including
   John Haggard, Mario Houthooft,  Frank Hoornaert, Hyon Im, Jan  Valcke
   and Richard  Vaden.  Mr. Houthooft  has  entered  into  a  consulting
   agreement with VDS NV/SA.  Neither Mr. Hunt nor  the Company's  other
   key personnel  have  entered  into  employment  agreements  with  the
   Company. As a  result, there are  no restrictions  on competition  by
   these individuals  (other than  Mr. Houthooft) after  termination  of
   employment or consulting services. Key man insurance in the amount of
   $1.5 million is currently maintained  by the Company  on the life  of
   Mr. Hunt but not on any of the  other key personnel. The loss of  the
   services of Mr. Hunt or one or more of its other key personnel  could
   have an  adverse  effect  on the  Company's  business  and  operating
   results.
<PAGE>
        The Company's  continued  success  is also  dependent  upon  its
   ability to  attract and  retain qualified  employees to  support  its
   future growth. Competition for such  personnel is intense, and  there
   can be no assurance that the Company can retain its key employees  or
   that it  can attract,  assimilate or  retain other  highly  qualified
   personnel in the future.

        (xv) Management and Control

        Control of the Company presently is largely in the hands of  its
   Board of Directors,  management and  T. Kendall  Hunt. As  of May  4,
   1998, the Board of Directors of  the Company and their spouses  owned
   beneficially and of record  approximately 56% (and  Mr. Hunt and  his
   family owned  beneficially  and of  record  51%) of  the  outstanding
   shares of the  Company's Common Stock.  Mr. Hunt is  Chairman of  the
   Board of  Directors, Chief  Executive Officer  and President  of  the
   Company. As a result, Mr. Hunt  will have control over the  direction
   and operation of  the Company  and with his  family will  be able  to
   elect the  directors of  the Company  and  to approve  any  corporate
   action requiring majority stockholder approval. Such concentration of
   control may  have  an adverse  effect  on  the market  price  of  the
   Company's Common Stock.

   Item 2 - Properties

        The   Company's   corporate    offices   and   North    American
   administrative, sales  and marketing,  research and  development  and
   support facilities  are located  in the  United States  in an  office
   complex in Oakbrook Terrace, Illinois,  a western suburb of  Chicago.
   These facilities are leased through November 15, 1999, and consist of
   approximately 10,000  square  feet.  The Company  believes  that  the
   Oakbrook Terrace facilities will be  adequate for its present  growth
   plans.

        The Company's  European  administrative,  sales  and  marketing,
   research and  development  and  support  facilities  are  located  in
   Belgium in an industrial park in  a southwestern suburb of  Brussels.
   These facilities  consist  of  approximately 10,000  square  feet  of
   office space which  are occupied under  a lease expiring  in July  of
   1999. The Company believes that these facilities are adequate through
   the term of the current lease and that on expiration of the lease  it
   will be able to either extend  the lease or find suitable  facilities
   at comparable rates.
<PAGE>
   Item 3 - Legal Proceedings

        The  Company  is   not  currently  involved   in  any   material
   litigation. However,  the Company  had a  product acceptance  dispute
   with  its  principal   customer  involving  the   sale  in  1995   of
   approximately $315,000 of certain  smartcard readers produced by  the
   Company in  response  to  written  specifications  submitted  by  the
   customer. This disagreement was settled during 1998 with a portion of
   the amount being credited to the customer ($85,000) and the remainder
   applied to future orders (this amount  will be determined based  upon
   the amount of product returned by  the customer, but in no case  will
   be  greater  than   $230,000).  Additionally,  the   Company  has   a
   disagreement with  certain  stockholders regarding  their  rights  as
   holders of warrants following the Exchange Offer.  As of the date  of
   this Annual Report on Form 10-K,  no litigation with respect to  this
   matter has been commenced, and the Company is unable to determine the
   extent of the matter's  adverse impact, if any,  upon its results  of
   operations or financial condition.

   Consulting Arrangement

        Mario Houthooft Consulting Agreement.  Mr. Houthooft was one  of
   the two principals of Lintel NV, the company that sold certain assets
   relating to data security products to Lintel Security, which was then
   acquired by VASCO Corp. Mr. Houthooft's services as Managing Director
   of VDS NV/SA are rendered pursuant  to a management agreement by  and
   between  VDS NV/SA   and  LINK   BVBA,  the   company  that   employs
   Mr. Houthooft. The  management  agreement  has  an  indefinite  term,
   although it is terminable by either party upon six months notice,  or
   without  prior  notice  upon  payment  of  a  specified  amount.  Mr.
   Houthooft is to  devote at  least forty-five  hours per  week to  his
   VDS NV/SA duties  pursuant  to  the agreement,  which  also  contains
   confidentiality  obligations   and  precludes   Mr.  Houthooft   from
   soliciting VDS NV/SA  employees or engaging  in competing  businesses
   during the term of the agreement. The agreement further provides that
   Mr. Houthooft will  not render services  to a competitor  or start  a
   competing business in Belgium, the  Netherlands and Luxembourg for  a
   one month period following termination of the agreement. In  addition
   to these restrictions, Mr. Houthooft is subject to a covenant not  to
   compete contained  in  the  Lintel  Security  acquisition  agreements
   pursuant to which Mr.  Houthooft agreed not  to compete, directly  or
   indirectly, with  VASCO  Corp. (or  any  of its  affiliates)  in  the
   manufacture and sale of  computer security products through  December
   31, 2001.


                                  PART II

   Item  5  -  Market  for   Registrant's  Common  Equity  and   Related
   Stockholder Matters
<PAGE>
        There was no established public market for the Company's  Common
   Stock in 1997.   On March  20, 1998, the  Company's Common Stock  was
   approved for trading  on the  NASD Electronic  Bulletin Board  system
   under the symbol "VDSI."

        On May 4, 1998, the closing sale price for the Company's  Common
   Stock, par value  $.001, on the  Over-the-Counter Bulletin Board  was
   $6.00 per  share.  Such Over-the-Counter  market  quotations  reflect
   inter-dealer prices, without retail mark-up, mark-down or  commission
   and may not necessarily  represent an actual  transaction. On May  4,
   1998, there were 85 registered holders of record of the Common Stock.

        The Company has not paid any dividends on its Common Stock since
   incorporation.  Dividends were paid relating to the Company's  Series
   B Preferred Stock, which was converted  to common stock in  September
   1997. Restrictions or limitations on the payment of dividends may  be
   imposed under the  terms of  credit agreements  or other  contractual
   obligations. In the absence of such restrictions or limitations,  the
   declaration and payment of dividends will  be at the sole  discretion
   of the  Board of  Directors of  the Company  and subject  to  certain
   limitations under  the  General  Corporation  Law  of  the  State  of
   Delaware.  The  timing, amount and  form of dividends,  if any,  will
   depend, among other things, on  the Company's results of  operations,
   financial condition, cash requirements, plans for expansion and other
   factors deemed  relevant by  the Board  of  Directors.   The  Company
   intends to retain  any future earnings  for use in  its business  and
   therefore does  not  anticipate  paying any  cash  dividends  in  the
   foreseeable future.

        In connection  with  the  Company's  organization,  the  Company
   issued 100 shares of its Common Stock to VASCO Corp. on July 16, 1997
   for an aggregate  consideration of  $100.   The 100  shares were  not
   registered under the Securities  Act of 1933,  as amended (the  "1933
   Act") and were issued  in reliance on Section  4(2) of the 1933  Act.
   No other securities were issued by the Company in 1997.

   Item 7 - Management's Discussion and Analysis of Financial  Condition
   and Results of Operations

        Certain  statements  contained  in  the  following  Management's
   Discussion  and  Analysis  of  Financial  Condition  and  Results  of
   Operations  are  forward-looking   statements.  All   forward-looking
   statements included herein are based on information available to  the
   Company on the date hereof and assumptions which the Company believes
   are reasonable. The Company does not assume any obligation to  update
   any such forward-looking statements. These forward-looking statements
   involve risks and uncertainties.  the Company's actual results  could
   differ materially  from those  anticipated in  these  forward-looking
   statements as a result of certain factors, including those set  forth
   in Subparagraph  d. of  Item  1 -  "Factors  That May  Affect  Future
   Results" and elsewhere in this Form 10-K.

        On March 11, 1998, VASCO Data Security International, Inc.  (the
   "Company") successfully completed its offer (the "Exchange Offer") to
   exchange the Company's shares, options, and warrants for VASCO  Corp.
   shares, options and warrants. Because the Company was a non-operating
   subsidiary of VASCO  Corp. prior to  the completion  of the  Exchange
   Offer (which occurred on March 11,  1998), the discussion of  results
   contained herein  relates  to the  results  of VASCO  Corp.  and  its
   subsidiaries.   Accordingly, references  to  "VASCO" shall  refer  to
   VASCO Corp. for periods prior to March 11, 1998.

   OVERVIEW

        VASCO designs, develops,  markets and  supports open  standards-
   based hardware and software security systems which manage and  secure
   access to data. VASCO's original corporate predecessor was founded in
   1984, and VASCO  entered the  data security  market in  1991 when  it
   acquired a controlling interest in what  is today one of VASCO's  two
   operating subsidiaries, VASCO Data  Security, Inc. ("VDS")  (formerly
   known as "ThumbScan,  Inc."), a  company that  designs, develops  and
   sells security  tokens, primarily  to  European customers.  In  1996,
   VASCO began developing  and marketing  open standards-based  security
   systems by introducing a hardware and software package, VACMan,  that
   is based on industry-accepted remote access protocols.

        Recent Acquisitions. In 1996,  VASCO significantly expanded  its
   presence in the European data security market through the acquisition
   of two Belgian companies, Lintel  Security (effective March 1,  1996)
   and Digipass SA  ("Digipass") (effective July  1, 1996), which  today
   comprise VASCO's  other  operating subsidiary,  VASCO  Data  Security
   NV/SA ("VDS NV/SA"). Both Lintel Security and Digipass at the time of
   acquisition were involved in designing, developing and marketing data
   security products, and Digipass  was to a  lesser extent involved  in
   developing interactive voice response ("IVR") products used primarily
   for telebanking  applications.  Lintel  Security  and  Digipass  were
   combined in  January  1997 and  renamed  VASCO Data  Security  NV/SA.
   During 1997, VDS  NV/SA entered  into an  agreement to  sell the  IVR
   business to  Siemens Societe  Anonyme ("Siemens")  for  approximately
   $200,000.
<PAGE>
        The acquisition  of  Lintel  Security was  accomplished  in  two
   steps. VASCO,  through VDSE,  acquired 15%  of the  capital stock  of
   Lintel Security in March of 1996, and then acquired the remaining 85%
   in June of 1996. As a  result, VASCO's consolidated results for  1996
   include 100% of Lintel Security's results  for the period from  March
   through June of 1996,  with a minority  interest elimination for  the
   85% not owned for this period, and 100% of Lintel Security's  results
   for the remainder of 1996, and all references to inclusion of  Lintel
   Security's results  since  the  date  of  acquisition  reflect  these
   percentage ownership figures for the appropriate time periods.

        The Lintel  Security purchase  involved a  cash payment  in  the
   amount of $289,482 and  the issuance of  (i) $747,500 in  convertible
   notes due May 30, 1998, (ii) 428,574 shares of VASCO's common  stock,
   and (iii) 100,000 warrants entitling the holders to purchase an equal
   number of shares of VASCO's common stock at $7.00 per share. The note
   bears interest  at  the  rate  of 8%  per  annum,  which  is  payable
   quarterly, in cash or shares of VASCO's common stock at the option of
   the holders. The notes can be converted at any time, at the option of
   the holders, into shares of VASCO's common stock at $7.00 per  share.
   The warrants were valued  at their fair value  at the date of  grant.
   These convertible notes and warrants  were exchanged pursuant to  the
   Exchange Offer and now represent  convertible notes and warrants  for
   the Company's Common Stock.

        The purchase of  Digipass was  a cash  transaction involving  an
   initial payment of $4,800,000 and an obligation to pay an  additional
   $3,400,000 on or before December 31, 1997. Underlying this obligation
   was a guarantee to  the seller of Digipass,  furnished by a  European
   commercial bank, which  was secured by  various personal and  company
   guarantees. VASCO renegotiated the guarantee into a convertible  loan
   due September  30, 2002  that  bears interest  at  a rate  of  3.25%,
   payable annually, and the  obligation to the  seller of Digipass  was
   paid in full in  August 1997. See  "Liquidity and Capital  Resources"
   below.

        Prior Lines  of  Business.  Before entering  the  data  security
   industry in 1991, VASCO's primary endeavor was providing  consulting,
   training and software services to various institutions in the  public
   and private  sectors through  VPS. In  1996,  VASCO sold  the  assets
   comprising this  line  of  business,  which  consisted  primarily  of
   contract rights, accounts receivable and training methodologies,  for
   consideration consisting of a royalty, payable to VASCO, equal to  5%
   of the gross training revenues of the purchaser in excess of $350,000
   per annum for a period of five years from the date of the sale. VASCO
   anticipates that the royalties, if any,  payable by the purchaser  of
   the VPS assets will be immaterial.

        Revenue and Earnings. The majority of sales made by VDS and  VDS
   NV/SA are in the  European markets, although  the Company intends  to
   actively pursue additional  markets outside  of Europe,  particularly
   Asia and North and South America.
<PAGE>
        Revenues  from  sales  of  security  tokens,  specifically   the
   AccessKey II and Digipass tokens, continue to represent the  majority
   of the Company's total revenues. In excess of 80% of VDS's sales  for
   1995, 1996 and 1997  were comprised of  security token devices,  with
   Concord-Eracom Nederland BV accounting for 92%, 97% and 67% of  VDS's
   sales in 1995, 1996 and 1997, respectively. On a consolidated  basis,
   the percentages  for 1995,  1996  and 1997  were  61%, 44%  and  16%,
   respectively, including revenues relating to the Lintel Security  and
   Digipass operations from their respective acquisition dates in  1996.
   It is expected that consolidated sales to other customers and markets
   will increase and, assuming this occurs, the degree of  concentration
   attributable to  this  major  customer will  decrease.  However,  the
   Company expects  that  this major  customer  will continue  to  be  a
   meaningful contributor to the Company's revenues and earnings for the
   foreseeable future. In 1998, for example, Concord-Eracom Nederland BV
   placed an additional $1.25 million order with VDS. Consequently,  the
   unforeseen loss  of this  customer's business,  or the  inability  to
   maintain reasonable profit  margins on  sales to  this customer,  may
   have an adverse  effect on the  Company's results  of operations  and
   financial condition.

        Although the  Company  believes  it  is  likely  that  sales  of
   security tokens, including  the newly introduced  Digipass 300,  will
   continue to account for  a majority of  the Company's total  revenues
   for the foreseeable future, the  Company also believes that  revenues
   from sales of its other hardware and software data security products,
   including the  additional  product  offerings made  possible  by  the
   Lintel Security and Digipass acquisitions, will continue to  increase
   in the future. No assurance, however, can be given that revenues will
   increase in the future.

   Research and Development.  The Company is  devoting its  capital
   and other resources to enhancing  its existing security products  and
   developing new  products  to  provide  enterprise-wide  hardware  and
   software security  solutions.  Costs  of  research  and  development,
   principally the design and development of hardware and software prior
   to the determination  of technological feasibility,  are expensed  as
   incurred on a project-by-project basis. The Company's  capitalization
   policy currently defines technological  feasibility as a  functioning
   beta test  prototype  with  confirmed  manufacturability  (a  working
   model), within a  reasonably predictable range  of costs.  Additional
   criteria include  receptive  customers, or  potential  customers,  as
   evidenced by interest  expressed in a  beta test  prototype, at  some
   suggested selling price.

        Once  technical  feasibility   has  been  established,   ongoing
   development costs  incurred  prior to  actual  sales of  the  subject
   product are  capitalized in  accordance with  Statement of  Financial
   Accounting Standards No.  86, "Accounting for  the Costs of  Computer
   Software  to  Be  Sold,   Leased  or  Otherwise  Marketed."   Product
   development costs are capitalized  on a product-by-product basis  and
   are amortized by  the greater  of (i)  the ratio  that current  gross
   revenues for a product bear to  the total of current and  anticipated
   future gross  revenues for  that product  or (ii)  the  straight-line
   method over the remaining estimated economic life of the product. The
   remaining estimated economic life of  these products are reviewed  at
   least quarterly.
<PAGE>
        Management has  concluded  that,  in  today's  rapidly  evolving
   technology markets and with the expanding  state of the computer  and
   network security  industry  in  general, it  may  be  impractical  to
   anticipate product life cycles in excess of two years.  Historically,
   however, the Company's products have experienced significantly longer
   product lives than two years.

        Variations  in  Operating   Results.  The  Company's   quarterly
   operating results have in the past varied and may in the future  vary
   significantly. Factors affecting operating results include: the level
   of competition;  the size,  timing, cancellation  or rescheduling  of
   significant orders;  market acceptance  of new  products and  product
   enhancements; new  product  announcements  or  introductions  by  the
   Company's competitors; adoption  of new  technologies and  standards;
   changes in pricing by the Company or its competitors; the ability  of
   the Company to develop, introduce and market new products and product
   enhancements on  a  timely basis,  if  at all;  component  costs  and
   availability; the  Company's  success  in  expanding  its  sales  and
   marketing programs;  technological changes  in  the market  for  data
   security products;  foreign  currency  exchange  rates;  and  general
   economic trends and other factors.   See Subparagraph d. of Item 1  -
   "Factors That May Affect Future Operating Results."

        In addition, the Company has experienced, and may experience  in
   the future, seasonality  in its  business. The  seasonal trends  have
   included higher revenue in the last quarter of the calendar year  and
   lower revenue in  the next succeeding  quarter. The Company  believes
   that revenue has tended to be higher  in the last quarter due to  the
   tendency of certain  customers to  implement or  complete changes  in
   computer or network security prior to  the end of the calendar  year.
   In addition, revenue  has tended to  be lower in  the summer  months,
   particularly  in  Europe,   when  many   businesses  defer   purchase
   decisions. Because  the Company's  operating  expenses are  based  on
   anticipated revenue levels  and a  high percentage  of the  Company's
   expenses are fixed, a small variation in the timing of recognition of
   revenue could cause significant variations in operating results  from
   quarter to quarter.

        Currency Fluctuations.  The majority  of  the supply  and  sales
   transactions of VASCO  Data Security,  Inc. are  denominated in  U.S.
   dollars, whereas many  of the supply  and sales  transactions of  VDS
   NV/SA are  denominated in  various foreign  currencies. In  order  to
   reduce the risks  associated with fluctuations  in currency  exchange
   rates, VDS NV/SA began in September 1997 to buy U.S. dollars based on
   three to  six months  estimated future  needs for  U.S. dollars,  has
   developed price lists  denominated in both  U.S. dollars and  foreign
   currencies, and  endeavors to  denominate its  new supply  and  sales
   transactions in U.S. dollars. In September 1997, VDS NV/SA  purchased
   $300,000 in U.S. dollars to cover purchases of supplies. VDS NV/SA is
   also beginning to attempt to match the timing of delivery, amount  of
   product and  the currency  denomination of  purchase orders  received
   from vendors with sales orders to  customers. See Subparagraph d.  of
   Item 1 - "Factors That May Affect Future Operating Results - Risks of
   International Operations."

   1997 COMPARED TO 1996

   The following discussion and analysis  should be read in  conjunction
   with VASCO's Consolidated  Financial Statements for  the years  ended
   December 31, 1997 and 1996.
<PAGE>
   Revenues

        VASCO's consolidated revenues  for the year  ended December  31,
   1997 were $12,302,000, an increase of $2,110,000, or 21%, as compared
   to the  year  ended  December  31,  1996.  VASCO  Europe  contributed
   $9,518,000, or 77%,  of total  consolidated revenues,  with VASCO  NA
   contributing the remaining  $2,784,000, or 23%.  Revenues (and  other
   operating results) attributable to VASCO Europe for 1996 are included
   only from the time of acquisition of Lintel Security and of Digipass.

        VASCO NA's  revenues were  $2,784,000 for  1997, a  decrease  of
   $2,034,000, or 42%,  as compared  to 1996  and accounted  for 23%  of
   consolidated revenues in  1997. The  decrease can  be attributed,  in
   part,  to  a  temporary  reduction  in  shipments  to  Concord-Eracom
   Nederland BV  during 1997.  Concord-Eracom Nederland  BV  represented
   approximately  $4,200,000  in  revenue  for  1996,  as  compared   to
   $2,000,000 in 1997.  However, during 1998 Concord-Eracom Nederland BV
   has placed  an  additional  order  with  VASCO  NA  of  approximately
   $1,250,000. VPS, the  former technical  and training  unit which  was
   sold in  August  of  1996,  had revenues  of  $204,000  in  1996  and
   accounted for 4% of VASCO's revenues in 1996.

   Cost of Goods Sold

        VASCO's consolidated  cost  of goods  sold  for the  year  ended
   December 31, 1997 was $6,287,000, an increase of $416,000, or 7%,  as
   compared to  the  year ended  December  31, 1996.  This  increase  is
   primarily attributable  to  the inclusion  of  VASCO Europe  for  the
   entire year 1997. VASCO Europe's cost  of goods sold was  $4,929,000,
   accounting for 78% of the consolidated cost of goods sold.

        VASCO  NA's  cost  of  goods   sold  was  $1,358,000  in   1997,
   representing a  decrease  of  $1,135,000, or  46%,  from  1996.  This
   decrease is consistent with the 42% decrease in revenues for the same
   period and,  as  discussed  above  under  "Revenues,"  is  due  to  a
   temporary reduction  in  shipments  to  Concord-Eracom  Nederland  BV
   during 1997. However, the  cost of goods  sold for security  products
   decreased as a percentage  at a slightly  quicker pace than  revenues
   for security products.  This is due  to certain  improvements in  the
   manufacture of  the products,  as well  as economies  of scale  being
   realized as the  1996 acquisitions  of Lintel  Security and  Digipass
   were fully integrated.

   Gross Profit

        VASCO's consolidated gross  profit for the  year ended  December
   31, 1997  was $6,015,000,  an increase  of $1,694,000,  or 39%,  over
   1996. This represents a consolidated gross margin of 49%, as compared
   to 1996's consolidated gross margin of 42%. VASCO Europe  contributed
   $4,589,000 to  the consolidated  gross  profit representing  a  gross
   margin of  48%  as compared  to  37% for  the  prior year.  VASCO  NA
   contributed $1,426,000  to  the  1997 gross  profit  as  compared  to
   $2,325,000 for 1996, a decrease of $899,000 or 39%. This  represented
   a gross margin  of 51% as  compared to 48%  for the  prior year.  The
   increase in  gross  margin is  due  to certain  improvements  in  the
   manufacture of  the products,  as well  as economies  of scale  being
   realized as the  1996 acquisitions  of Lintel  Security and  Digipass
   were fully integrated.
<PAGE>
   Sales and Marketing Expenses

        Consolidated sales  and marketing  expenses for  the year  ended
   December 31,  1997 were  $3,381,000, an  increase of  $1,976,000,  or
   141%, over 1996. The  increase can be attributed  to the addition  of
   VASCO  Europe  for  the  full  year  1997;  increased  sales  efforts
   including, in part, increased travel costs; an increase in  marketing
   activities, including print media campaigns and other efforts, and an
   increased presence at trade shows.

   Research and Development

        Consolidated R&D costs for the year ended December 31, 1997 were
   $1,802,000, an increase of  $1,228,000, or 214%,  as compared to  the
   year  ended  December  31,  1996.   R&D  costs  represented  15%   of
   consolidated revenues  for  1997 as  compared  to 6%  for  1996.  The
   increase is due to  the addition of R&D  headcount, both in the  U.S.
   and Europe, and to the acquisition  of the VACMan product from  Shiva
   Corporation and the related integration efforts surrounding it.   R&D
   efforts are undertaken by both VASCO NA and VASCO Europe on behalf of
   the consolidated group  of companies. Whereas  VASCO NA is  primarily
   responsible for the development of software products, VASCO Europe is
   responsible for hardware development. Consequently, management of the
   Company believes it is not meaningful to address R&D costs separately
   at the operating company level.

        VASCO expensed, as cost of goods  sold, $0 and $180,000 in  1997
   and 1996, respectively,  reflecting the  amortization of  capitalized
   development costs. As of  December 31, 1997 and  1996, VASCO did  not
   carry any product development costs on  its books as an asset.  There
   were no product development costs capitalized in 1997 or 1996.

   General and Administrative Expenses

        Consolidated general and  administrative expenses  for the  year
   ended December 31, 1997 were  $4,768,000, an increase of  $1,120,000,
   or 31%, over 1996. The majority of this increase can be attributed to
   the  legal,  accounting  and  printing  costs  associated  with   the
   preparation of  the Exchange  Offer held  by the  Company during  the
   first quarter  of 1998.  In addition,  the  full-year impact  of  the
   Lintel Security  and Digipass  acquisitions and  the amortization  of
   intangibles associated with those acquisitions increased general  and
   administrative expenses in 1997.

   Acquired In-process Research and Development

        During 1996,  VASCO expensed  $7,351,000 pertaining  to the  in-
   process research and development acquired in the Lintel Security  and
   Digipass   acquisitions.   Based    upon   independent    appraisals,
   approximately 67% of  the acquisition  premium has  been expensed  in
   accordance with U.S. Generally Accepted Accounting Principles. As  of
   December  31,  1997,  there  remains  a  net  balance  of  $2,314,000
   representing the intangible assets related to the acquisitions, which
   are carried on VASCO's books and  amortized over an additional  18-66
   months. Amortization expenses amounted to $1,083,000 and $440,000 for
   the years ended December 31, 1997 and 1996, respectively.
<PAGE>
   Operating Loss

        VASCO's consolidated operating loss for the year ended  December
   31, 1997 was $3,935,000, compared to the consolidated operating  loss
   of $8,658,000 for 1996. Of the 1997 loss, VASCO NA contributed a loss
   in the amount of  $4,130,000 and VASCO  Europe contributed income  in
   the amount of $195,000. The 1996 consolidated operating loss included
   a write-off of  acquired in-process research  and development in  the
   amount of $7,351,000 and $440,000 of amortization expense relating to
   intangible assets in 1996. The 1996 operating loss, before the write-
   off and the amortization, was $867,000.

        VASCO's 1997  operating  loss,  excluding  the  amortization  of
   intangibles,  was  attributable  to   continued  investment  in   R&D
   (primarily for  Digipass 300),  sales  and marketing  investments  in
   North  America,   the   expenses   for   development   of   corporate
   infrastructure, such as sales personnel and administrative staff  and
   office equipment,  and  the  legal,  accounting  and  printing  costs
   incurred during 1997 associated with the preparation of the  Exchange
   Offer held by the Company during the first quarter of 1998.

   Interest Expense

        Consolidated interest expense in 1997 was $1,148,000 compared to
   $346,000  in  1996.  The  increase  can  be  attributed  to   average
   borrowings in  1997 being  substantially above  those levels  of  the
   previous year. See "Liquidity and Capital Resources" below.

   Income Taxes

        VASCO recorded tax expense for the year ended December 31,  1997
   of $200,000  for VASCO  NA and  $407,000 for  VASCO Europe.  The  tax
   expense recorded for VASCO NA represents the revaluation (write-down)
   of deferred tax assets.  As of December 31,  1997, VASCO reflected  a
   net deferred tax asset of $83,000, which represented the amount  that
   management deemed would  more likely than  not be  realized. The  net
   deferred tax  asset was  net of  a valuation  allowance of  $831,000,
   which  was  established  during   1996  and  adjusted  during   1997,
   considering  the  effects  of  reversing  deferred  tax  liabilities,
   projected future  earnings, which  were  revised substantially  as  a
   result of the acquisitions of Lintel  Security and Digipass, and  tax
   planning strategies.

        At December 31, 1997, VASCO had net operating loss carryforwards
   of  $4,722,000   and  foreign   net  operating   loss   carryforwards
   approximating $1,025,000, which may be used to offset future  taxable
   income of VASCO  generated in the  United States.  The net  operating
   loss carryforwards expire  in various amounts  beginning in 2002  and
   continuing through 2012.
<PAGE>
   Dividends and Accumulated Deficit

        VASCO paid dividends  of $82,000 and  $108,000 during the  years
   ended December  31,  1997  and  1996,  respectively.  These  dividend
   payments  were  attributable  to  9,000  shares  of  VASCO  Series  B
   Preferred Stock  issued in  1994. During  1997, all  9,000 shares  of
   VASCO Series B Preferred Stock were converted into VASCO Corp. common
   stock.  VASCO began 1997 with  an accumulated deficit of  $9,903,000.
   As a  result of  the 1997  net loss,  this deficit  has increased  to
   $15,902,000. VASCO's 1997 increase in accumulated deficit can be attributed
   primarily to increased legal, accounting and printing costs  incurred
   during 1997 associated with the Exchange  Offer held by VASCO  during
   the first quarter of 1998, the amortization of intangibles related to
   the 1996  acquisitions of  Lintel  Security and  Digipass,  strategic
   marketing programs implemented during 1997 and a product acquisition.

   1996 COMPARED TO 1995

   The following discussion and analysis  should be read in  conjunction
   with VASCO's Consolidated  Financial Statements for  the years  ended
   December 31, 1996 and 1995.

   Revenues

        VASCO's consolidated revenues  for the year  ended December  31,
   1996 were  $10,192,000,  an  increase  of  $6,497,000,  or  176%,  as
   compared  to  the  year  ended   December  31,  1995.  VASCO   Europe
   contributed $5,374,000, or  53%, of total  consolidated revenues.  Of
   the  $5,374,000   total  revenues   contributed  by   VASCO   Europe,
   $5,180,000, or 96%,  represent data security  product revenues,  with
   the remaining $194,000,  or 4%,  representing revenues  from the  IVR
   products. Revenues  (and  other operating  results)  attributable  to
   VASCO Europe are included only from the time of acquisition of Lintel
   Security and of Digipass.

        VASCO NA's revenues  were $4,818,000  for 1996,  an increase  of
   $1,118,000, or 30%,  as compared  to 1995  and accounted  for 47%  of
   consolidated revenues  in  1996.  Security  product  sales  increased
   $2,157,000 to $4,614,000  in 1996, representing  a 88% increase  over
   1995. Conversely, VPS, the former  technical and training unit  which
   was sold  in  August of  1996,  had  revenues of  $204,000  in  1996,
   representing a decrease  of $1,034,000,  or 84%,  for the  comparable
   period in 1995. VPS accounted for  just 4% of VASCO NA's revenues  in
   1996, down from 33% in 1995.

   Cost of Goods Sold

        Consolidated cost of goods sold for the year ended December  31,
   1996 was $5,871,000, an increase of $2,984,000, or 103%, as  compared
   to the  year ended  December 31,  1995.  This increase  is  primarily
   attributable to the acquisition of VASCO Europe in 1996 and offset to
   some extent by a decrease in VASCO NA's combined cost of goods  sold.
   VASCO Europe's cost of goods sold was $3,378,000, accounting for  58%
   of the consolidated cost of goods sold.
<PAGE>
        VASCO  NA's  cost  of  goods   sold  was  $2,493,000  in   1996,
   representing a decrease of $394,000, or 14%, from 1995. This decrease
   was primarily a  result of a  decrease of  $814,000, attributable  to
   VPS's operations prior to its disposal. This was partially offset  by
   an increase in  cost of goods  sold related to  security products  of
   $420,000. VASCO NA's  cost of goods  sold for  security products  was
   $2,453,000 in 1996, as compared  to $2,033,000 in 1995,  representing
   an increase of  21%. The  cost of  goods sold  for security  products
   increased as a percentage less  than revenues for security  products.
   This is due  to certain  non-recurring costs  related to  capitalized
   development costs (approximately $350,000) and inventory  write-downs
   (approximately $100,000) included in the cost of goods sold for 1995.

        The non-recurring charge  for capitalized  development costs  in
   the fourth quarter of  1995 related to  several PC security  products
   that were not expected to generate future revenues. In addition,  two
   authentication products were  deemed to  have a  shorter useful  life
   than  originally   estimated  resulting   in  the   acceleration   of
   amortization expense  as a  result of  the  change in  estimate.  The
   useful lives  were  reduced  due to  technological  advances  in  the
   market, as well as VASCO's development activities with regard to  its
   AKII successor product (Digipass 300).

        The non-recurring inventory write-downs  resulted in the  fourth
   quarter of 1995 from management's review of discontinued products and
   various electronic components. As a  result of this review,  reserves
   were established to  write-down the  inventory to  its estimated  net
   realizable value.

   Gross Profit

        VASCO's consolidated gross  profit for the  year ended  December
   31, 1996 was  $4,321,000, an increase  of $3,513,000,  or 435%,  over
   1995. This represents a consolidated gross margin of 42%, as compared
   to 1995's consolidated gross margin of 22%. VASCO Europe  contributed
   $1,996,000 to  the consolidated  gross  profit representing  a  gross
   margin of  37%. VASCO  NA contributed  $2,325,000 to  the 1996  gross
   profit as compared to $808,000 for 1995, an increase of $1,517,000 or
   188%. Data security  products accounted for  93% of  VASCO NA's  1996
   gross profit due to  the reduction in VPS  activity and the  eventual
   disposition of  VPS  during the  year.  Data security  products  only
   accounted for 57% of  gross profit during  1995, with VPS  accounting
   for the remaining 43% of gross profit.

        VASCO NA's gross  margin increased in  1996 to 46%  from 22%  in
   1995. This is  attributable to  1995 non-recurring  costs related  to
   capitalized development costs  and write-down  of certain  inventory,
   and increased sales of higher margin security products as opposed  to
   lower margin VPS services.
<PAGE>
   Sales and Marketing Expenses

        Consolidated sales  and marketing  expenses for  the year  ended
   December 31,  1996 were  $1,405,000, an  increase of  $1,160,000,  or
   473%, over 1995.  Of the  total increase,  $548,000, or  47%, can  be
   attributed to  the  addition of  VASCO  Europe. Sales  and  marketing
   expenses increased by $612,000, or 250%,  for VASCO NA. The  increase
   for VASCO NA can be attributed to increased sales efforts, including,
   in part,  the addition  of four  sales people,  and increased  travel
   costs; an  increase in  marketing activities,  including print  media
   campaigns and  other  efforts, and  an  increased presence  at  trade
   shows.

   Research and Development

        Consolidated R&D costs for the year ended December 31, 1996 were
   $575,000, an increase of $333,000, or  138%, as compared to the  year
   ended December 31,  1995. R&D  costs represented  6% of  consolidated
   revenues for 1996,  approximately the  same percentage  as 1995.  R&D
   efforts are undertaken by both VASCO NA and VASCO Europe on behalf of
   the consolidated group  of companies. Whereas  VASCO NA is  primarily
   responsible for the development of software products, VASCO Europe is
   responsible for hardware development. Consequently, management of the
   Company believes it is not meaningful to address R&D costs separately
   at the operating company level.

        VASCO expensed, as cost of goods sold, $180,000 and $445,000  in
   1996  and  1995,   respectively,  reflecting   the  amortization   of
   capitalized development costs.  In the fourth  quarter of 1995  VASCO
   accelerated the  amortization  of capitalized  development  costs  to
   reflect an  adjustment  to the  estimated  economic life  of  certain
   products. The accelerated  portion of 1995  amortization amounted  to
   approximately $350,000.

        Net product development  costs carried  on VASCO's  books as  an
   asset were $0  and $157,000  at December  31, 1996  and December  31,
   1995,  respectively.  There   were  no   product  development   costs
   capitalized in 1996 or 1995.
   General and Administrative Expenses

        Consolidated general and  administrative expenses  for the  year
   ended December 31, 1996 were  $3,648,000, an increase of  $2,793,000,
   or 326%, over 1995. Of the total increase, $1,426,000, or 51%, can be
   attributed  to   the   addition   of  VASCO   Europe.   General   and
   administrative expenses increased by  $1,367,000, or 160%, for  VASCO
   NA. The increase  for VASCO NA  can be attributed  to an increase  in
   administrative infrastructure to support  the efforts of other  areas
   of the VASCO, as well as amortization of intangibles associated  with
   the acquisitions of Lintel Security and Digipass.
<PAGE>
   Acquired In-process Research and Development

        VASCO expensed, as an  operating expense, $7,351,000  pertaining
   to the in-process  research and  development acquired  in the  Lintel
   Security  and   Digipass   acquisitions.   Based   upon   independent
   appraisals, approximately 67% of the acquisition premium was expensed
   in accordance with U.S. Generally Accepted Accounting Principles.  As
   of December 31, 1996, there remained $3,372,000 of intangible  assets
   related to the acquisitions  which will be  carried on VASCO's  books
   and be amortized over an additional  30 - 78 months. As noted  above,
   $440,000 of the intangible assets were amortized to expense in 1996.

   Operating Loss

        VASCO's consolidated operating loss for the year ended  December
   31, 1996 was $8,658,000, compared to the consolidated operating  loss
   of $534,000 for 1995. The 1996 consolidated operating loss included a
   write-off of  acquired in-process  research  and development  in  the
   amount of $7,351,000 and the $440,000 of intangible assets  amortized
   to expense in 1996. The operating loss, before the write-off and  the
   amortization of intangibles expensed,  was $867,000. Of this  amount,
   VASCO NA contributed a loss of $911,000 and VASCO Europe  contributed
   net operating income of $44,000.

        VASCO's 1996 operating  loss, before the  write-off of  acquired
   in-process  research  and   development  and   the  amortization   of
   intangibles expensed, was attributable to continued investment in R&D
   (primarily for  Digipass 300),  sales  and marketing  investments  in
   North  America,  one-time  professional  fees  associated  with   the
   acquisitions of  Lintel  Security  and  Digipass,  the  expenses  for
   development of corporate infrastructure, such as sales personnel  and
   administrative staff and office equipment, and, in general, the costs
   associated with consolidating  and assimilating  the Lintel  Security
   and
   Digipass acquisitions.

   Interest Expense

        Consolidated interest expense in  1996 was $346,000 compared  to
   $74,000 in 1995. The increase can be attributed to average borrowings
   in 1996 being substantially above those levels of the previous  year.
   See "Liquidity and Capital Resources" below.

   Income Taxes
        VASCO recorded tax expense for the year ended December 31,  1996
   of $162,000  for VASCO  NA  and $32,000  for  VASCO Europe.  The  tax
   expense recorded for VASCO NA represents the revaluation (write-down)
   of deferred tax assets.  As of December 31,  1996, VASCO reflected  a
   net deferred tax asset of $283,000, which represented the amount that
   management deemed would  more likely than  not be  realized. The  net
   deferred tax  asset was  net of  a valuation  allowance of  $631,000,
   which  was  established  during  1996,  considering  the  effects  of
   reversing deferred tax liabilities, projected future earnings,  which
   were revised substantially as a result of the acquisitions of  Lintel
   Security and Digipass, and tax planning strategies.
<PAGE>
        VASCO has net operating loss  carryforwards of $1,626,000 as  of
   December 31, 1996, which may be used to offset future taxable  income
   of VASCO  generated in  the United  States.  The net  operating  loss
   carryforwards  expire  in  various  amounts  beginning  in  2010  and
   continuing through 2011.

   Dividends and Accumulated Deficit

        VASCO paid dividends of $108,000 in each of 1996 and 1995. These
   dividend payments were attributable to 9,000 shares of VASCO Series B
   Preferred Stock issued in 1994. VASCO began 1996 with an  accumulated
   deficit of $554,000. As a result  of the 1996 net loss, this  deficit
   increased to $9,903,000.

        VASCO's 1996 loss  before taxes,  the resulting  net loss  after
   taxes, and  the resulting  increase in  accumulated deficit,  can  be
   attributed primarily  to  the  acquisitions of  Lintel  Security  and
   Digipass and  the  write-off  of  acquired  in-process  research  and
   development.  The  write-off  of  acquired  in-process  research  and
   development accounted for 81% of VASCO's 1996 loss before taxes.

   RECENT DEVELOPMENTS

        Loan Agreement/License  Agreement.    On  March  31,  1998,  the
   Company entered into  two agreements  with Lernout  & Hauspie  Speech
   Products N.V. ("L&H"): a loan agreement and a license agreement.  The
   loan agreement, in the  amount of $3 million,  bears interest at  the
   Prime Rate  plus 1%,  payable quarterly,  and matures  on January  4,
   1999. This  loan is  convertible at  the option  of the  holder  into
   shares of the Company's Common Stock  based upon the average  closing
   price of VASCO Corp.'s common stock for the 10 trading days prior  to
   March 11, 1998,  the date the  Exchange Offer closed.  This loan  was
   funded in April 1998.

        The license agreement with  L&H is for the  use of L&H's  speech
   recognition and  speech verification  technology for  data  security,
   telecom and  physical access  applications.   This license  agreement
   includes a prepayment of  royalties by the Company  in the amount  of
   $600,000, payable  no later  than June  30,  1998 and  an  additional
   prepayment in the amount of $200,000, payable no later than March 31,
   1999. L&H is an international leader  in the development of  advanced
   speech technology for various commercial applications and products.

   LIQUIDITY AND CAPITAL RESOURCES

        Since inception,  VASCO has  financed its  operations through  a
   combination of the issuance of equity securities, private borrowings,
   short-term commercial  borrowings,  cash flow  from  operations,  and
   loans from Mr. T. Kendall Hunt,  VASCO's Chief Executive Officer  and
   one of the stockholders of its original corporate predecessor.

        In 1995, VASCO borrowed $130,000 from  Mr. Hunt, resulting in  a
   total loan payable balance of $190,000 at the end of 1995. This  loan
   was repaid in  1996 from the  proceeds of  private placements  during
   1996.
<PAGE>
        Also during  1995, VASCO  privately placed  units consisting  of
   217,352 shares of VASCO's common stock and 108,676 VASCO Warrants  to
   purchase one share of VASCO common stock at $6.00. The VASCO Warrants
   are exercisable at the option of the holder; however, VASCO maintains
   the right to  require exercise  of the warrants  30 days  prior to  a
   public offering of VASCO's common stock.  Total issue fees and  costs
   of $22,261 have  been netted against  $369,498 of  proceeds from  the
   placement.

        Of the  total  108,676 units  issued  in the  private  placement
   described in the immediately  preceding paragraph, 53,000 units  were
   sold to  a  group  of investors  subject  to  a  Registration  Rights
   Agreement ("Rights Agreement") entered into on October 19, 1995.  The
   agreement required  that  the  common  stock  portion  of  the  units
   (106,000 shares) be  covered by an  effective registration  statement
   under the Securities Act by July 1, 1996. The described remedy in the
   event of default was a put option (the "put"), allowing the investors
   to exchange their units for consideration of $7.00 per unit, or $3.50
   per common share. Due to a  delay in making the required filing  with
   the Securities and Exchange Commission, VASCO agreed to an  extension
   and renegotiation  of  the  Rights  Agreement.  This  resulted  in  a
   requirement for  an effective  registration  statement on  or  before
   March 31, 1997 and an increase in  the put price to $14.00 per  unit,
   or $7.00 per share. This filing  deadline also was not satisfied  and
   VASCO and the investor group entered into an amended agreement  under
   which (i) the investors "put" approximately one-third of their shares
   (35,328 shares) back to VASCO  with payments totaling $247,261  being
   remitted to the  investor group,  (ii) additional  VASCO Warrants  to
   purchase an aggregate of  141,344 shares of VASCO  common stock at  a
   price of $5.19 per  share were granted to  the investor group,  (iii)
   the March 31, 1997 deadline  for an effective registration  statement
   was changed to March 31, 1998,  and (iv) the investor group  received
   the right to put their shares to VASCO if after March 7, 1997,  VASCO
   raises financing of $5,000,000 or more. These warrants were exchanged
   pursuant to the  Exchange Offer and  now represent  warrants for  the
   Company's Common Stock. [The Company and the investor group  disagree
   as to the applicability of certain provisions of the Rights Agreement
   following the Exchange Offer.]

        During the second quarter of 1996, VASCO placed additional units
   consisting of  666,666  shares  of VASCO  common  stock  and  137,777
   warrants, each of which entitles the holder to purchase one share  of
   VASCO common  stock at  $4.50. The  private placement  of shares  and
   warrants generated gross proceeds of $3,000,000. In addition, in  the
   same transaction, VASCO borrowed  $5,000,000 and issued a  $5,000,000
   convertible note due on May 28, 2001. The note bears interest at  9%,
   with interest payable to the holder on a quarterly basis. The  holder
   may, at its  option, elect to  receive interest payments  in cash  or
   Common Stock. In calculating the shares  of VASCO common stock to  be
   issued in lieu of cash interest, the average closing price for shares
   of VASCO common stock  for the previous 20  trading days is used.  In
<PAGE>
   the event VASCO receives funds equal  to or greater than  $30,000,000
   from a public offering of its  Common Stock, the holder of this  note
   has the right to require VASCO to pay all amounts due and owing under
   the note within 30 days of receipt by VASCO of notice from the holder
   of exercise of  this right. Total  issue fees and  costs of  $170,000
   related to the equity  portion of this  transaction have been  netted
   against the $3,000,000 of proceeds from the equity private placement.
   In addition,  55,555 shares  of VASCO  common stock  and 8,889  VASCO
   Warrants, each of which entitles the holder to purchase one share  of
   VASCO common stock at  $4.50, were issued  as commissions related  to
   the placement. These warrants were exchanged pursuant to the Exchange
   Offer and now represent warrants for the Company's Common Stock.

        The proceeds from the  $8,000,000 private placement  ($3,000,000
   equity and $5,000,000 debt) were used  to make the first  installment
   of $4,800,000  toward  the  Digipass purchase,  to  satisfy  one-time
   expenses related to the Lintel Security and Digipass acquisitions, to
   retire VASCO's debt to its commercial lender and to Mr. Hunt, and  to
   fund working capital requirements in general.

        In 1996, VASCO raised additional funds in a private placement of
   units consisting of 237,060 shares of  VASCO common stock and  35,329
   VASCO Warrants, each  of which entitles  the holder  to purchase  one
   share of VASCO common stock at  $4.50. Total issue fees and costs  of
   $47,885 were netted against the $1,066,770 in total proceeds from the
   placement in VASCO's financial statements. In addition, 16,489 shares
   of VASCO  common stock  were issued  as  commissions related  to  the
   placement. These  warrants were  exchanged pursuant  to the  Exchange
   Offer and now represent warrants for the Company's Common Stock.

        The net effect of 1996 activity resulted in an increase in  cash
   of $1,069,000, resulting in a cash balance of $1,814,000 at  December
   31, 1996, compared to  $745,000 at the end  of 1995. VASCO's  working
   capital  at  December  31,  1996  was  $4,902,000,  an  increase   of
   $3,828,000, or 356%, from $1,074,000 at the end of 1995. The majority
   of the  improvement is  attributable to  an increase  in all  current
   asset categories, aided by the addition of VASCO Europe's assets  and
   the private placements made  during the year,  offset with the  final
   payment  related  to  the  Digipass  acquisition  in  the  amount  of
   $3,400,000. VASCO's  current ratio  was 2.32  at December  31,  1996,
   compared to 2.01 at the end of 1995.

        Effective in June  1997, VASCO  established a  bridge loan  with
   Generale  Bank  in  the  amount  of  $2,500,000,  evidenced  by  five
   convertible notes in the amount of $500,000 each. Upon completion  of
   the Exchange Offer, the Company became obligated for all  obligations
   under the loan and the notes. These notes bear interest at a rate  of
   3.25%, payable quarterly, and  are due September  30, 1998, at  which
   time 116% of  the principal amount  becomes due and  payable. In  the
   event the Company completes a public offering prior to September  30,
   1998, the holder of a note has the option within seven days after the
   completion of a public offering to  require the note to be repaid  at
   100% of  the principal  amount thereof  in cash  or in  Common  Stock
   (valued at  the public  offering price),  at the  holder's  election,
   together with  all  accrued  and  unpaid  interest  to  the  date  of
   repayment  plus  additional  special  interest  payable  in  cash  as
<PAGE>
   follows: $88,235 if repayment  is between January  1, 1998 and  March
   31, 1998, both dates inclusive; and $125,000 if repayment is  between
   April 1, 1998 and  September 30, 1998, both  dates inclusive. In  the
   event that the holder  of the note does  not elect within seven  days
   after completion of  the public offering  to require the  note to  be
   repaid, the holder  may at any  time thereafter (until  the close  of
   business on  the  September  30,  1998  maturity  date)  require  the
   principal amount of the note to  be repaid in shares of Common  Stock
   (valued at  the  public  offering  price)  plus  accrued  and  unpaid
   interest to the date of repayment (but no additional special interest
   shall be payable).  If the notes  have not been  repaid prior to  the
   September 30, 1998 maturity date, and the Company fails to repay  the
   note prior to  November 1, 1998,  then on and  from November 1,  1998
   (but before payment of the note), in the event a public offering  has
   not been completed  the bank may  convert the  principal amount  into
   shares of the Company's Common Stock (i) at a conversion price  equal
   to a historical  20 day  trading price in  the United  States if  the
   stock is listed or quoted on  the Nasdaq, Easdaq or another  national
   U.S.  stock  exchange,  plus  the  payment  of  $250,000  in  special
   interest, payable in  cash or shares  at the option  of the bank,  or
   (ii) if the shares are not so listed, at a conversion price of $1.00.
   VASCO also issued warrants entitling the bank to acquire an aggregate
   of 40,000 shares of VASCO's common  stock at exercise prices  ranging
   from $4 to  $10 per  share, which  warrants became  warrants for  the
   Company's Common Stock upon completion  of the Exchange Offer.  These
   notes are expected to be renegotiated upon maturity.

        The net effect of 1997 activity resulted in an increase in  cash
   of $84,000, resulting in a cash balance of $1,898,000 at December 31,
   1997, compared  to $1,814,000  at the  end of  1996. VASCO's  working
   capital  at  December  31,  1997   was  $1,945,000,  a  decrease   of
   $2,957,000, or 60%, from $4,902,000 at the end of 1996. The  majority
   of the change  is attributable  to a  decrease in  all current  asset
   categories with  the  exception  of cash,  with  current  liabilities
   remaining consistent from  year to  year. VASCO's  current ratio  was
   1.51 at December 31, 1997, compared to 2.32 at the end of 1996.

        VDSE entered  into  a  convertible loan  agreement  with  Banque
   Paribas Belgique S.A. effective August,  1997, in order to  refinance
   the $3.4 million  payment due December  31, 1997  in connection  with
   VASCO's acquisition of Digipass. The  terms of the agreement  provide
   that the $3.4 million principal amount is convertible, at the  option
   of the lender, into shares of  the Company's Common Stock. This  loan
   bears interest at the rate of 3.25%, payable annually, and matures on
   September 30,  2002.  The  loan is  convertible,  commencing  on  the
   earlier of January 1, 1999  or the date of  a public offering of  the
   Company's shares  on  the EASDAQ  and/or  NASDAQ and  terminating  on
   August 31, 2002, at a conversion price equal to the per share  public
   offering price,  provided,  however, that  if  no such  offering  has
   occurred prior to January  1, 1999, and the  loan is converted  after
   such date but prior to a public offering, the conversion price is the
   average closing market price for shares of the Company's Common Stock
   on the NASD Electronic Bulletin Board system for the 20 trading  days
<PAGE>
   prior to the date of the notice of conversion, less 10%. In the event
   a public offering  is completed,  the lender  may at  its option  (by
   written notice  within seven  days after  receipt by  the Company  of
   proceeds of the public offering) require the principal amount of  the
   loan to be repaid in cash, in which case additional special  interest
   is payable as follows: $340,000 if repayment is on or before June 30,
   1998, $510,000 if repayment is between July 1, 1998 and December  31,
   1998 (both dates inclusive), and $680,000 if repayment is on  January
   1, 1999 or later.

        The Company intends to seek acquisitions of businesses, products
   and technologies that are complementary or  additive to those of  the
   Company. While from time to time  the Company engages in  discussions
   with respect to  potential acquisitions,  the Company  has no  plans,
   commitments or agreements with respect to any such acquisitions as of
   the date of this  Form 10-K and currently  does not have excess  cash
   for use in making  acquisitions. There can be  no assurance that  any
   such acquisition will be made.

        The  Company  believes  that  its  current  cash  balances   and
   anticipated cash revenues from operations will be sufficient to  meet
   its anticipated cash needs through December 31, 1998. Continuance  of
   the Company's  operations beyond  December  31, 1998,  however,  will
   depend on the Company's ability to obtain adequate financing. To this
   end, in March 1998, the Company entered into a loan agreement in  the
   amount of  $3 million  with Lernout  & Hauspie  Speech Products  N.V.
   ("L&H"); the funding  of this loan  is occurred early  in the  second
   quarter of 1998. The loan bears interest at the highest "prime  rate"
   published in The Wall Street Journal under the heading "Money  Rates"
   on such day  plus 1%, payable  quarterly, and matures  on January  4,
   1999. L&H is an international leader  in the development of  advanced
   speech technology for various  commercial applications and  products.
   The loan  is convertible  at the  option of  L&H into  shares of  the
   Company's Common Stock at the rate of $5.6813 per share (based on the
   average closing  price of  VASCO Corp.'s  common  stock for  the  ten
   trading days prior to March 12, 1998).

        L&H and  VASCO  have agreed  to  work together  to  apply  L&H's
   patented  voice   technology  in   various  applications   of   voice
   authentication.  VASCO's  first application is  for data and  network
   security, authenticating the user through a voiceprint, matching only
   to a specific individual's pre-recorded voice .  Voice authentication
   will compliment VASCO's  other methods  of authentication,  providing
   strong, yet flexible  choices for  the end  customer.   It will  also
   allow  VASCO  to  reach  markets  that  it  currently  cannot  serve,
   presenting new opportunities for growth.

        The Company has also entered into engagement letters with Banque
   Paribas S.A. and Generale Bank for a possible future public offering.
   Further, the Company has had preliminary discussions regarding  other
   possible debt  or  equity  financing.  There  can  be  no  assurance,
   however, that the Company  will be successful  in effecting a  public
   offering or obtaining other additional financing.

   YEAR 2000 CONSIDERATIONS
<PAGE>
        Many existing computer systems  and software products are  coded
   to accept only two digit entries in the date code field with  respect
   to year.  With the  21st century less than  two years away, the  date
   code field  must be  adjusted to  allow for  a four  digit year.  The
   Company believes that its internal  systems are Year 2000  compliant,
   but the Company  will need  to take the  required steps  to make  its
   existing products  compliant.    The total  estimated  cost  of  this
   exercise is $100,000, with an anticipated completion date of December
   31, 1998. There can be no  assurance, however, that the Company  will
   meet its anticipated completion date or that the total cost will  not
   exceed $100,000. The Company believes that the purchasing patterns of
   customers and potential customers may be affected by Year 2000 issues
   as companies expend  significant resources to  upgrade their  current
   software systems  for Year  2000 compliance.   This,  in turn,  could
   result in reduced  funds available to  be spent  on other  technology
   applications, such as those offered by the Company, which could  have
   a material adverse effect  on the Company's  business and results  of
   operations.

   RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

        In June  1997, the  Financial Accounting  Standard Board  issued
   SFAS No.  130,  "Reporting Comprehensive  Income."   The  Company  is
   required to adopt SFAS No. 130  for periods beginning after  December
   15,  1997.    This  statement  establishes  standards  for  reporting
   comprehensive income and  its components in  a full  set of  general-
   purpose financial statements.  The  standard requires all items  that
   are  required  to  be   recognized  under  accounting  standards   as
   components  of  comprehensive  income  be  reported  in  a  financial
   statement that  is  displayed  in equal  prominence  with  the  other
   financial statements.    The  standard is  not  expected  to  have  a
   material impact on the Company's current presentation of income.

        In June  1997, the  Financial  Accounting Standards  Board  also
   issued SFAS No. 131, "Disclosures about Segments of an Enterprise and
   Related  Information."    The  Company  is  required  to  adopt   the
   disclosures of  SFAS No.  131 beginning  with its  December 31,  1998
   annual financial statements.   This  statement establishes  standards
   for the  way  companies are  to  report information  about  operating
   segments.   It also  establishes  standards for  related  disclosures
   about products and  services, geographic areas  and major  customers.
   The Company is currently  evaluating the impact  of this standard  on
   its financial statements.

        In November  1997, the  American Institute  of Certified  Public
   Accountants issued Statement of Position ("SOP") No. 97-2,  "Software
   Revenue Recognition."  The Company is  required to adopt SOP 97-2  on
   January 1, 1998.  SOP 97-2 is intended to reduce diversity in current
   revenue recognition  practices within  the  software industry.    The
   Company is  currently  evaluating the  effects  of SOP  97-2  on  its
   operations.

                                VASCO CORP.
                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


   Note 1 - Summary of Significant Accounting Policies

   Nature of Operations

        VASCO Corp.  and  its  wholly  owned  subsidiaries,  VASCO  Data
   Security, Inc., and VASCO Data Security NV/SA (the Company), offer  a
   variety of computer  security products and  services.  The  Company's
   patented and  proprietary  hardware  and  software  products  provide
   computer security,  Advanced  Authentication Technology  and  RSA/DES
   encryption for financial institutions, industry and government.   The
   primary market for these products is Europe.

   Use of Estimates

        The preparation  of  financial  statements  in  conformity  with
   generally accepted accounting principles requires management to  make
   estimates and assumptions that affect the reported amounts of  assets
   and liabilities and disclosure  of contingent assets and  liabilities
   at the date of the financial  statements and the reported amounts  of
   revenues and expenses  during the reporting  period.  Actual  results
   could differ from those estimates.

   Principles of Consolidation

        The consolidated financial  statements include  the accounts  of
   VASCO Corp.  and  its wholly  owned  subsidiaries.   All  significant
   intercompany  accounts  and  transactions  have  been  eliminated  in
   consolidation.
<PAGE>
   Revenue Recognition

        Revenues  from  the  sale  of  computer  security  hardware  and
   imbedded software are recorded upon shipment. No significant  Company
   obligations exist  with regard  to  delivery or  customer  acceptance
   following shipment.

   Property and Equipment

        Property and  equipment are  stated at  cost.   Depreciation  is
   computed using  the straight-line  method over  the estimated  useful
   lives of  the  related assets  ranging  from three  to  seven  years.
   Additions and improvements  are capitalized,  while expenditures  for
   maintenance and repairs are charged to  operations as incurred.   The
   cost and accumulated  depreciation of  property sold  or retired  are
   removed from  the  respective accounts  and  the resultant  gains  or
   losses, if any, are included in current operations.

   Software Costs

        The Company capitalizes software development costs in accordance
   with Statement  of  Financial  Accounting Standards  (SFAS)  No.  86.
   Research  and  development  costs,  prior  to  the  establishment  of
   technological feasibility, determined  based upon the  creation of  a
   working model, are expensed as incurred.  The Company's policy is  to
   amortize capitalized  costs by  the greater  of  (a) the  ratio  that



   current gross revenues for a product bear to the total of current and
   anticipated future  gross  revenues  for  that  product  or  (b)  the
   straight-line method over  the remaining estimated  economic life  of
   the product, generally two to five years, including the period  being
   reported on.    Unamortized capitalized  costs  determined to  be  in
   excess of the net realizable value  of a product are expensed at  the
   date of such determination.

        The Company expensed $444,795, $180,275 and $0 in 1995, 1996 and
   1997, respectively,  for  the amortization  of  capitalized  software
   costs.

   Income Taxes

        Income taxes are  accounted for  under the  asset and  liability
   method.  Deferred tax assets and  liabilities are recognized for  the
   future tax  consequences  attributable  to  differences  between  the
   financial  statement  carrying   amounts  of   existing  assets   and
   liabilities and their respective tax bases and operating loss and tax
   credit carryforwards.    Deferred  tax  assets  and  liabilities  are
   measured using enacted tax rates expected to apply to taxable  income
   in the years in which those temporary differences are expected to  be
   recovered or  settled.    The  effect  on  deferred  tax  assets  and
   liabilities of a change in tax  rates is recognized in income in  the
   period that includes the enactment date.
<PAGE>
   Fair Value of Financial Instruments and Long-Lived Assets

        The  following  disclosures  of  the  estimated  fair  value  of
   financial instrument are made in accordance with the requirements  of
   SFAS No. 107, "Disclosures and Fair Value of Financial  Instruments."
   The estimated fair value amounts have been determined by the  Company
   using  available   market  information   and  appropriate   valuation
   methodologies.    The   fair  values  of   the  Company's   financial
   instruments were not materially different from their carrying amounts
   at December 31, 1996 and 1997, except for notes payable and long-term
   debt, for which the fair value is not determinable.

        On  January  1,  1996,  the   Company  adopted  SFAS  No.   121,
   "Accounting for the  Impairment of  Long-Lived Assets  and for  Long-
   Lived Assets to be Disposed Of," under which the Company has reviewed
   long-lived assets and certain  intangible assets and determined  that
   their carrying  values as  of December  31, 1997  are recoverable  in
   future periods.

   Stock-Based Compensation

        On  January  1,  1996,  the   Company  adopted  SFAS  No.   123,
   "Accounting for Stock-Based Compensation," which permits entities  to
   recognize the compensation expense associated with the fair value  of
   all stock-based awards on the date of grant.  Alternatively, SFAS No.
   123 allows entities to continue to apply the provisions of Accounting
   Principles Board (APB)  Opinion 25, "Accounting  for Stock Issued  to
   Employees," and provide pro forma net  income and earnings per  share
   disclosures as if the fair value  method defined in SFAS No. 123  had
   been applied.  The Company has elected to apply the provisions of APB
   Opinion 25 and provide the pro forma disclosures of SFAS No. 123.

   Foreign Currency Translation and Transactions
       
        The  financial  position  and  results  of  operations  of   the
   Company's foreign subsidiaries are measured using the local  currency
   as the functional currency.  Accordingly, assets and liabilities  are
   translated into U.S. dollars using current  exchange rates as of  the
   balance sheet date.  Revenues and expenses are translated at  average
   exchange rates prevailing during  the year.  Translation  adjustments
   arising from differences in exchange rates are included as a separate
   component of stockholders' equity.   Gains and losses resulting  from
   foreign  currency  transactions  are  included  in  the  consolidated
   statements of operations.

   Goodwill

        Goodwill is amortized on a straight-line basis over the expected
   period to be  benefited, which is  seven years.   Adjustments to  the
   carrying value of  goodwill are made  if the sum  of expected  future
   undiscounted net cash flows from the  business acquired is less  than
   the book value of goodwill.
<PAGE>
   Loss Per Common Share

        In the fourth quarter of 1997, the Company adopted SFAS No. 128,
   "Earnings Per Share," which established new methods for computing and
   presenting earnings per share  ("EPS") and replaced the  presentation
   of primary and  fully-diluted EPS  with basic  ("Basic") and  diluted
   EPS.   Basic earnings  per share  is based  on the  weighted  average
   number of  shares outstanding  and excludes  the dilutive  effect  of
   unexercised common stock equivalents.  Diluted earnings per share  is
   based on  the  weighted  average number  of  shares  outstanding  and
   includes the dilutive effect of unexercised common stock equivalents.
   Because the Company reported a net loss for the years ended  December
   31, 1995, 1996 and 1997, per share amounts have been presented  under
   the basic method only.

        Had the  Company  reported  net earnings  for  the  years  ended
   December 31,  1995, 1996  and 1997,  the weighted  average number  of
   shares  outstanding  would  have  potentially  been  diluted  by  the
   following common equivalent securities  (not assuming the effects  of
   applying the treasury  stock method to  outstanding stock options  or
   the if-converted method to convertible securities):

                                        =========   =========   =========
</TABLE>
   * Due to  the contingent nature  of the conversion  feature of  these
   notes, a  20-day  average market  price  was used  to  calculate  the
   diluted number of shares.

        Additionally, net earnings applicable to common stockholders for
   the years ended December 31, 1996 and 1997 would have been  increased
   by interest expense related to the convertible notes of $265,450  and
   $980,250, respectively.


   Note 2 - Acquisitions

        Effective March 1, 1996, the Company acquired a 15% interest  in
   Lintel NV  (Lintel).   On  June 1,  1996,  the Company  acquired  the
   remaining 85% of Lintel.  Lintel, located in Brussels, Belgium, was a
   developer of security technologies  for personal computers,  computer
   networks  and   telecommunications   systems,   using   cryptographic
   algorithms such as DES and RSA.   The results of Lintel's  operations
   are included in  the Company's consolidated  statement of  operations
   from March 1, 1996  with minority interest  being reflected in  other
   expense in the  consolidated statement  of operation  for the  period
   from March  1,  1996  to  June  1, 1996.    The  purchase  price  was
   $4,432,000,  consisting  of   $289,482  in  cash,   $747,500  in   8%
<PAGE>
   convertible notes payable due May 30, 1998 and convertible to  common
   stock at a rate of $7.00  per share, 428,574 shares of the  Company's
   common stock valued at $7.00 per share, and 100,000 purchase warrants
   for the Company's common  stock at an exercise  price of $7.00.   The
   warrants were recorded at their fair value on the date of grant.
   The acquisition  of  Lintel was  accounted  for as  a  purchase  and,
   accordingly,  the  acquired  assets  have  been  recorded  at   their
   estimated fair values at the date  of the acquisition.  Acquired  in-
   process research  and development  in the  amount of  $2,900,000  was
   expensed during 1996 in conjunction with the acquisition, based  upon
   an independent  third-party  valuation.   Goodwill  related  to  this
   transaction was $387,000, which is being  amortized over a period  of
   seven years.

        Effective July  1,  1996,  the Company  acquired  Digipass  s.a.
   (Digipass).   Digipass,  located  in  Belgium,  was  a  developer  of
   security technologies for personal  computers, computer networks  and
   telecommunications systems  using  the DES  cryptographic  algorithm.
   Prior to the  Company's acquisition of  Digipass, the  assets of  the
   interactive  voice  response  (IVR)  business  of  Digiline  SA  were
   transferred to Digipass.  Digipass'  IVR products are used  primarily
   in telebanking  applications  and  in  corporate  authentication  and
   access control technology.  The  purchase price was $8,200,000,  with
   $4,800,000 being paid at the effective  date of acquisition, and  the
   balance of $3,400,000 in the form of a note, which was paid in August
   1997.

        The acquisition of Digipass was accounted for as a purchase and,
   accordingly, the acquired assets  and liabilities have been  recorded
   at their  estimated  fair values  at  the date  of  the  acquisition.
   Acquired  in-process  research  and  development  in  the  amount  of
   $4,451,000 was expensed during 1996, based upon an independent third-
   party valuation.  Goodwill related to this transaction was  $491,000,
   which is being amortized over a  period of seven years.  The  results
   of operations for  Digipass have  been included  in the  consolidated
   statement of operations subsequent to July 1, 1996.



        Other assets,  resulting from  the  acquisitions of  Lintel  and
   Digipass, are comprised  of the following  at December  31, 1997  and
   1996 (net of accumulated amortization):

<PAGE>
        Software and  hardware  technology  is being  amortized  over  a
   period of three to four years while workforce and customer lists  are
   being amortized over a period of seven years.  Amortization of  these
   assets was $374,892  and $943,207 for  the years  ended December  31,
   1996 and 1997, respectively.  Included in the 1997 amortization is  a
   write-down in  the amount  of $234,493  related to  the workforce  of
   Digipass, due to attrition realized during the year.

        The following unaudited pro forma summary presents the Company's
   results of  operations as  if the  acquisitions has  occurred at  the
   beginning of  1996.    This summary  is  provided  for  informational

        The Company uses multiple suppliers for the microprocessors used
   in the production of hardware products,  as well as for the  assembly
   of the products.  The microprocessors are the only components of  the
   Company's hardware  devices that  would be  considered  non-commodity
   items and may not be readily available on the open market.  There is,
   however,  an  inherent   risk  associated  with   each  supplier   of
   microprocessors.  In order to  increase orders of microprocessors,  a
   lead time of 12 weeks is  typically needed.  The Company maintains  a
   sufficient inventory  of all  component  parts to  handle  short-term
   spikes in order quantities.

   Note 5 - Income Taxes

        At December  31,  1997,  the  Company  has  net  operating  loss
   carryforwards approximating $4,722,000 and foreign net operating loss
   carryforwards approximating $1,025,000.  Such losses are available to
   offset future taxable income at VASCO  Corp. and its U.S.  subsidiary
   and expire  in  varying  amounts beginning  in  2002  and  continuing
   through 2012.   In addition, if  certain substantial  changes in  the
   Company's ownership should occur, there would be an annual limitation
   on the amount of the carryforwards which could be utilized. In fiscal
   1995, the Company had no current tax provision due to the utilization
   of approximately $66,000 of loss carryforward benefits.

        Pretax  loss  from  continuing  operations  was  taxed  in   the
   following jurisdictions:

</TABLE>
        The net change in  the total valuation  allowance for the  years
   ended December 31,  1996 and  1997 was  an increase  of $631,000  and
   $1,779,000, respectively.  In assessing the realizability of deferred
   tax assets, the Company considers whether it is more likely than  not
   that some portion or all of the deferred tax assets will be realized.
   The ultimate realization of deferred tax assets is dependent upon the
   generation of future taxable income during the period in which  these
   temporary  differences  become  deductible.    This  assessment   was
   performed  considering  the  scheduled   reversal  of  deferred   tax
   liabilities,  projected  future  taxable  income,  and  tax  planning
   strategies.  The Company has determined  that it is more likely  than
   not that  $83,000 of  deferred  tax assets  will  be realized.    The
   remaining valuation allowance of $2,410,000 is maintained on deferred
   tax assets which  the Company has  not determined to  be more  likely
   than not  realizable  as  of  December  31,  1997.    This  valuation
   allowance will be reviewed on a regular basis and adjustments made as
   appropriate.

        In June 1997, the Company entered into a new financing agreement
   with a European bank.  The new agreement provides for $2.5 million in
   financing, matures on September 30, 1998, bears interest at a rate of
   3.25% annually and is convertible into common stock of the Company at
   the option of  the bank,  at conversion  prices as  specified in  the
   agreement. In the event the Company completes a public offering prior
   to September 30,  1998, the holder  of a note  has the option  within
   seven days after the completion of  a public offering to require  the
   note to be repaid at 100% of the principal amount thereof in cash  or
   in common  stock  (valued  at the  public  offering  price),  at  the
   holder's election, together with all  accrued and unpaid interest  to
   the date of  repayment plus  additional special  interest payable  in
   cash as follows: $88,235 if repayment is between January 1, 1998  and
   March 31, 1998 and $125,000 if repayment is between April 1, 1998 and
   September 30, 1998.

        In August 1997, the  Company renegotiated the guarantee  related
   to the final payment for the 1996 acquisition of Digipass into a term
   loan in the amount  of $3.4 million.   The note matures on  September
   30, 2002 and bears interest at a rate of 3.25% annually. In the event
   a public offering is completed, the lender may at its option  require
   the principal amount of the loan to be repaid in cash, in which  case
   additional special  interest  is  payable  as  follows:  $340,000  if
   repayment is on  or before June  30, 1998, $510,000  if repayment  is
   between July 1, 1998 and December 31, 1998 and $680,000 if  repayment
   is on January 1, 1999 or later. In addition, the note is  convertible
   into common stock  of the Company  at the option  of the  bank, at  a
   conversion prices as specified in the agreement.

        During 1996,  the  Company  acquired two  companies  located  in
   Europe (see Note 2).   To facilitate  the first acquisition,  Lintel,
   one  component  of  the  purchase   price  was  represented  by   two
   convertible notes, each payable in  the amount of $373,750  ($747,500
   total) due May 30, 1998.   The notes are convertible at the  holders'
   option at a rate of $7.00 per share of common stock. During 1996  and
   1997,  these  notes   were  paid   down  by   $33,750  and   $76,829,
   respectively.  Each of these notes bears an interest rate of 8%, with
   interest payments made on a quarterly basis.  At the holders' option,
   the interest may be  paid either in  cash or in  common stock of  the
   Company.  In calculating the shares  of common stock to be issued  in
   lieu of cash interest,  the average closing  price for the  Company's
   common stock for the previous 20 trading days is used.

        During 1996, the Company  continued to raise capital  privately,
   including a private placement consisting  of the issuance of  666,666
   shares of common stock and a $5,000,000 convertible note due May  29,
   2001.  The note  bears interest at 9%,  with interest payable to  the
   holder on a quarterly basis.  The holder may, at its option, elect to
   receive interest payments in  cash or common  stock.  In  calculating
   the shares of common stock to be issued in lieu of cash interest, the
   average closing price for the Company's common stock for the previous
   20 trading days is used.

   Aggregate maturities of debt at December 31, 1997 are as follow:

   with one warrant  to purchase  one share  of common  stock at  $6.00.
   Included in the 108,676 equity units are 53,000 equity units  subject
   to redemption, at the option of the  holder, at a price of $7.00  per
   share, or $14.00  per equity unit.   In March  1997, 17,664 of  these
   equity units (representing 35,328 shares  of common stock and  17,664
   warrants) were  redeemed  at  $14.00 per  equity  unit,  with  70,667
   warrants to purchase one share of common stock at $5.19 being  issued
   to the holders of the redeemed units.

        In July 1997, the Company reissued 2,824 shares of common  stock
   from treasury and 778,383 original  issue shares in conjunction  with
   the conversion of the  117,181 Series A  Shares (see Preferred  Stock

   shares of  common stock  in conjunction  with the  conversion of  the

   the exercise of  options under the  Company's incentive stock  option
   plan (see Note 8)  for total proceeds of  $42,470;  16,489 shares  of
   common stock that had been issued in December 1996 were  subsequently
   canceled; and 116,218 shares of common  stock were issued in lieu  of
   interest related  to the  $5,000,000 convertible  note placed  during
   1996 (see Note 6).

        During 1996,  the Company  reissued 287,923  shares of  treasury
   stock, issued 140,651 shares of common stock and 100,000 warrants  to
   purchase one  share  of  common stock  at  $7.00  as a  part  of  the
   acquisition of Lintel (see  Note 2).  The  warrants were recorded  at
   their fair value  on the  date of grant.   In  addition, the  Company
   continued to raise  money through  private placements  of its  common
   stock.  In the  first quarter of 1996,  the Company privately  placed
   167,482 shares of common  stock and 83,741  warrants to purchase  one
   share of common stock at $6.00, generating $284,720 in net  proceeds.
   The warrants are exercisable  at the option  of the holder,  however,
   the Company maintains the right to  require exercise of the  warrants
   30 days prior to a public offering of the Company's stock.

        During the second  quarter of 1996,  the Company placed  666,666
   shares of common stock with 137,777 warrants to purchase one share of
   common stock at $4.50.  Total  issue fees and costs of $170,000  have
   been netted against $3,000,000 of proceeds from the placement in  the
   Company's financial statements.  In addition, 55,555 shares of common
   stock and 8,889  warrants to purchase  one share of  common stock  at
   $4.50 were issued as commissions related to the placement.
<PAGE>
        The Company  raised  additional  funds  in  1996  in  a  private
   placement of 237,060 shares of common  stock with 35,329 warrants  to
   purchase one share of  common stock at $4.50.   Total issue fees  and
   costs of $47,885  have been netted  against the  $1,066,770 in  total
   proceeds from the  placement in the  Company's financial  statements.
   In addition, 16,489 shares of common stock were issued as commissions
   related to the placement, but were canceled in 1997.

   issued in  lieu of  an interest  payment in  the amount  of  $118,750
   related to the private debt placement that occurred during 1996  (see
   Note 6).


   Note 8 - Stock Option Plan

        The Company's 1987 Stock Option Plan, as amended, (Option  Plan)
   is designed and intended as a performance incentive.  The Option Plan
   is administered by  the Compensation  Committee as  appointed by  the
   Board of Directors of the Company (Compensation Committee).

        The Option Plan permits the grant of options to employees of the
   Company to purchase  shares of common  stock intended  to qualify  as
   incentive stock options  under Section  422 of  the Internal  Revenue
   Code of 1986, as  amended (Code).  All  options granted to  employees
   are for a period of ten  years, are granted at  a price equal to  the
   fair market value of the  common stock on the  date of the grant  and
   are vested 25% on  the date of  grant and an  additional 25% on  each
   subsequent anniversary of the grant.

        The  Option  Plan  further  permits  the  grant  of  options  to
   directors, consultants  and  other  key  persons  (non-employees)  to
   purchase shares of common stock not intended to qualify as  incentive
   stock options under the Code.   All options granted to  non-employees
   are for a period of ten  years, are granted at  a price equal to  the
   fair market value of the common stock  on the date of the grant,  and
   may contain vesting requirements and/or restrictions as determined by
   the Compensation Committee at the time  of grant.  These options  are
   vested 50% six months from the date of grant and the remaining 50% on
   the first anniversary of the date of grant.

        During 1996,  the Compensation  Committee increased  the  shares
   authorized under the Option Plan by 500,000 to 3,000,000.
<PAGE>
        The  Company   applies   APB   Opinion  No.   25   and   related
   interpretations in accounting for the Option Plan.  Had  compensation
   cost for the  Option Plan been  determined consistent  with SFAS  No.
   123, the Company's net loss available to common stockholders and  net
   loss per common share would have been the pro forma amounts indicated
   below:

</TABLE>
        For purposes  of calculating  the compensation  cost  consistent
   with SFAS No. 123, the fair  value of each option grant is  estimated
   on the date  of grant  using the  Black-Scholes option-pricing  model
   with the following  weighted-average assumptions used  for grants  in
   fiscal  1995,  1996  and  1997:    dividend  yield  of  0%;  expected
   volatility of 50%;  risk free interest  rates ranging  from 6.29%  to
   6.80%; and expected lives of five years.

        Rent expense  under  operating leases  aggregated  approximately
   $60,000, $158,000 and $213,000 for the years ended December 31, 1995,
   1996 and 1997, respectively.

        During a period of time extending from the mid-1980s to the mid-
   1990s the  Company  engaged  in certain  matters  that  were  not  in
   compliance with requisite corporate law.  There have been no lawsuits
   asserted or  filed  against the  Company  related to  these  matters.
   Management cannot assess the likelihood that a lawsuit would be filed
   nor can management estimate a potential range of loss.

        The Company is  subject to  legal proceedings  and claims  which
   have arisen in the ordinary course of its business and have not  been
   finally adjudicated.   These actions, when  ultimately concluded  and
   determined, will not, in the opinion  of management, have a  material
   adverse impact on the financial  position, results of operations  and
   liquidity of the Company.

        Exchange Offer.  VASCO Data Security International, Inc.  ("VDSI
   Inc.") was  organized in  1997  as a  subsidiary  of VASCO  Corp.,  a
   Delaware corporation ("VASCO Corp.").  Pursuant to an exchange  offer
   ("Exchange Offer") by VDSI  Inc. for securities  of VASCO Corp.  that
   was completed March 11, 1998, VDSI Inc. acquired 97.7% of the  common
   stock of VASCO Corp.  Consequently,  VASCO Corp. became a  subsidiary
   of VDSI Inc.,  with the remaining  2.3% of  VASCO Corp.  shareholders
   representing a minority interest.

        Loan Agreement/License Agreement.  On March 31, 1998, the
   Company entered into two agreements with Lernout & Hauspie Speech
   Products N.V. ("L&H"), consisting of a loan agreement and a license
   agreement. The loan agreement, in the amount of $3 million, bears
   interest at the prime rate plus 1%, payable quarterly, and matures on
   January 4, 1999. This loan is convertible at the option of the holder
   into shares of the Company's common stock based upon the average
   closing price of VASCO Corp.'s common stock for the 10 trading days
   prior to March 11, 1998, the date the Exchange Offer closed. This
   loan was funded in April 1998.

        The license agreement with L&H is for the use of L&H's speech
   recognition and speech verification technology for data security,
   telecom and physical access applications.  This license agreement
   includes a prepayment of royalties by the Company in the amount of
   $600,000, payable no later than June 30, 1998 and an additional
   prepayment in the amount of $200,000, payable no later than March 31,
   1999. L&H is an international leader in the development of advanced
   speech technology for various commercial applications and products.

                       INDEPENDENT AUDITORS' REPORT

   The Stockholders and Board of Directors
   VASCO Corp.:

        We have audited the accompanying consolidated balance sheets of
   VASCO Corp. and subsidiaries (the "Company") as of December 31, 1996
   and 1997 and the related statements of operations, stockholders'
   equity (deficit), and cash flows for each of the years in the three-
   year period ended December 31, 1997.  These consolidated financial
   statements are the responsibility of the Company's management.  Our
   responsibility is to express an opinion on these consolidated
   financial statements based on our audits.

        We conducted our audits in accordance with generally accepted
   auditing standards.  Those standards require that we plan and perform
   the audit to obtain reasonable assurance about whether the financial
   statements are free of material misstatement.  An audit includes
   examining, on a test basis, evidence supporting the amounts and
   disclosures in the financial statements.  An audit also includes
   assessing the accounting principles used and significant estimates
   made by management, as well as evaluating the overall financial
   statement presentation.  We believe that our audits provide a
   reasonable basis for our opinion.

        In our opinion, the financial statements referred to above
   present fairly, in all material respects, the financial position of
   VASCO Corp. and subsidiaries as of December 31, 1996 and 1997, and
   the results of their operations and their cash flows for each of the
   years in the three-year period ended December 31, 1997, in conformity
   with generally accepted accounting principles.

                            AMENDED BY-LAWS

                       ARTICLE I - STOCKHOLDERS


   Section 1.  Annual Meeting

        To the extent required by applicable  law, an annual meeting  of
   the stockholders,  for the  election of  directors to  succeed  those
   whose terms expire and for the transaction of such other business  as
   may properly come before the meeting, shall be held at such place, on
   such date, and at such time as the Board of Directors shall each year
   fix, which date  shall be within  thirteen months  subsequent to  the
   later of the  date of  incorporation or  the last  annual meeting  of
   stockholders.

   Section 2.  Special Meetings

        Special  meetings  of  the  stockholders,  for  any  purpose  or
   purposes prescribed in the  notice of the meeting,  may be called  by
   the Board of Directors  or the Chief Executive  Officer and shall  be
   held at such  place, on such  date, and at  such time as  they or  he
   shall fix.

   Section 3.  Notice of Meetings

        Written notice of the place, date,  and time of all meetings  of
   the stockholders shall  be given,  not less  than ten  nor more  than
   sixty days before the  date on which  the meeting is  to be held,  to
   each  stockholder  entitled  to  vote  at  such  meeting,  except  as
   otherwise provided  herein  or required  by  law (meaning,  here  and
   hereinafter, as required from time to time by the General Corporation
   Law of the State of Delaware or the Certificate of Incorporation).

        When a meeting  is adjourned to  another place,  date, or  time,
   written notice need  not be  given of  the adjourned  meeting if  the
   place, date, and time thereof are  announced at the meeting at  which
   the adjournment is taken; provided, however, that, if the date of any
   adjourned meeting is more than thirty  days after the date for  which
   the meeting was originally noticed, or if a new record date is  fixed
   for the adjourned  meeting, written notice  of the  place, date,  and
   time of the adjourned meeting shall be given in conformity  herewith.
    At any adjourned meeting, any business may be transacted which might
   have been transacted at the original meeting.

   Section 4.  Quorum

        Except as otherwise provided  by law or  these by-laws, at  each
   meeting of stockholders  the presence in  person or by  proxy of  the
   holders of a majority  in voting power of  the outstanding shares  of
   stock entitled  to  vote  at  the  meeting  shall  be  necessary  and
   sufficient to constitute a  quorum.  In the  absence of a quorum  the
   chairman of the meeting or the stockholders so present (by a majority
   in voting power thereof) may adjourn the meeting from time to time in
<PAGE>
   the manner provided in Section 3 of Article I of these by-laws  until
   a quorum shall  attend.   Shares of its  own stock  belonging to  the
   corporation or to another  corporation, if a  majority of the  shares
   entitled  to  vote  in  the  election  of  directors  of  such  other
   corporation is  held, directly  or  indirectly, by  the  corporation,
   shall neither be entitled to vote nor be counted for quorum purposes;
   provided, however, that the  foregoing shall not  limit the right  of
   the corporation or any subsidiary of  the corporation to vote  stock,
   including but not limited to its own stock, held by it in a fiduciary
   capacity.

   Section 5.  Organization

        Such person as the Board of Directors may have designated or, in
   the absence of  such a  person, the  highest ranking  officer of  the
   corporation who is  present shall call  to order any  meeting of  the
   stockholders and act as chairman of  the meeting.  In the absence  of
   the Secretary of the corporation, the secretary of the meeting  shall
   be such person as the chairman appoints.

   Section 6.  Conduct of Business

        The chairman of any meeting of stockholders shall determine  the
   order of business and  the procedure at  the meeting, including  such
   regulation of the manner of voting  and the conduct of discussion  as
   seem, to him, in order.

   Section 7.  Proxies and Voting

        At any meeting of  the stockholders, every stockholder  entitled
   to vote may vote, in person or by proxy.

        Each stockholder shall have  one vote for  every share of  stock
   entitled to vote which is registered  in his name on the record  date
   for the meeting, except as otherwise  provided herein or required  by
   law.

        All voting,  except  on  the election  of  directors  and  where
   otherwise required by law, may be by a voice vote; provided, however,
   that upon demand therefor  by a stockholder entitled  to vote or  his
   proxy, a stock vote shall be taken.  Every stock vote shall be  taken
   by ballots, each of which shall state the name of the stockholder  or
   proxy voting and such other information as may be required under  the
   procedure established for the meeting.   Every vote taken by  ballots
   shall be  counted by  an inspector  or  inspectors appointed  by  the
   chairman of the meeting.

        All elections shall be  determined by a  plurality of the  votes
   cast, and, except  as otherwise required  by law,  all other  matters
   shall be determined by a majority of the votes cast.
<PAGE>
   Section 8.  Stock List

        A complete list of stockholders entitled to vote at any  meeting
   of stockholders, arranged  in alphabetical  order for  each class  of
   stock and showing the address of each such stockholder and the number
   of shares registered in his name, shall be open to the examination of
   any such stockholder, for any purpose germane to the meeting,  during
   ordinary business hours for a period of at least ten (10) days  prior
   to the meeting, either at a  place within the city where the  meeting
   is to be held, which  place shall be specified  in the notice of  the
   meeting, or, if not so specified,  at the place where the meeting  is
   to be held.

        The stock list shall  also be kept at  the place of the  meeting
   during the whole time thereof and shall be open to the examination of
   any such stockholder who is present.   This list shall  presumptively
   determine the identity of  the stockholders entitled  to vote at  the
   meeting and the number of shares held by each of them.

   Section 9.  Nomination of Directors. 

        Any stockholder nominating a person  for election as a  director
   must comply with  the procedures set  forth herein.   Nominations  of
   persons for election to the Board of Directors of the corporation may
   be made at a  meeting of stockholders (a) by  or at the direction  of
   the Board of Directors or (b) by  any stockholder of the  corporation
   who is  a stockholder  of record  at  the time  of giving  of  notice
   provided for in this Section 9, who shall be entitled to vote for the
   election of directors at the meeting and who complies with the notice
   procedures set forth in this Section 9.  Such nominations, other than
   those made by or at the direction of the Board of Directors, shall be
   made pursuant to  timely notice in  writing to the  Secretary of  the
   corporation.  To be timely, a stockholder's notice shall be delivered
   to or mailed and received at  the principal executive offices of  the
   corporation not less than 60 days nor more than 90 days prior to  the
   meeting; provided, however, that in the event that less than 70 days'
   notice or prior public disclosure of the date of the meeting is given
   or made to stockholders, notice by the stockholder to be timely  must
   be so received not later than the  close of business on the 10th  day
   following the day on which such notice of the date of the meeting  or
   such public disclosure was made.  Such stockholder's notice shall set
   forth (a) as to each person whom the stockholder proposes to nominate
   for election or reelection as a director all information relating  to
   such person  that is  required to  be disclosed  in solicitations  of
   proxies for election of directors, or is otherwise required, in  each
   case pursuant to Regulation 14A under the Securities Exchange Act  of
   1934, as amended  (including such person's  written consent to  being
   named in  the  proxy statement  as  a nominee  and  to serving  as  a
   director if elected); and (b) as to the stockholder giving the notice
   (i) the name and address, as they appear on the corporation's  books,
   of such stockholder and (ii) the class  and number of shares of   the
   corporation which are beneficially owned by such stockholder.  At the
   request of the Board of Directors, any person nominated by the  Board
   of Directors  for  election  as  a  director  shall  furnish  to  the
   Secretary of  the corporation  that information  required to  be  set
   forth in a stockholder's notice of  nomination which pertains to  the
   nominee.  No person nominated by  a stockholder shall be eligible  to
   serve as a director of the corporation unless nominated in accordance
<PAGE>
   with the procedures set  forth in this By-Law.   The Chairman of  the
   meeting shall, if  the facts warrant,  determine and  declare to  the
   meeting that  a  nomination  was not  made  in  accordance  with  the
   procedures prescribed by the By-Laws, and  if the Chairman should  so
   determine and declare to the meeting, the defective nomination  shall
   be disregarded.   Notwithstanding  the foregoing  provisions of  this
   Section 9, a  stockholder  shall  also  comply  with  all  applicable
   requirements of the Securities Exchange Act of 1934, as amended,  and
   the rules and regulations thereunder with respect to the matters  set
   forth in this Section 9.  Nothing herein shall limit or restrict  the
   right of the Board of Directors  to nominate persons for election  as
   directors or to elect directors in accordance with these By-Laws.

   Section 10.  Notice of Business. 

        At any meeting of the stockholders, only such business shall  be
   conducted as shall have been brought before the meeting (a) by or  at
   the direction of the Board of Directors or (b) by any stockholder  of
   the corporation who is a stockholder of record at the time of  giving
   of the notice provided for in this Section 10, who shall be  entitled
   to vote at such meeting and  who complies with the notice  procedures
   set forth in this  Section 10.  For business  to be properly  brought
   before a stockholder meeting by  a stockholder, the stockholder  must
   have given timely notice thereof in  writing to the Secretary of  the
   Corporation.  To be timely, a stockholder's notice must be  delivered
   to or mailed and received at  the principal executive offices of  the
   corporation not less than 60 days nor more than 90 days prior to  the
   meeting; provided, however, that in the event that less than 70 days'
   notice or prior public disclosure of the date of the meeting is given
   or made to stockholders, notice by the stockholder to be timely  must
   be received  no later  than the  close of  business on  the 10th  day
   following the day on which such notice of the date of the meeting was
   mailed or, if earlier, the date  on which such public disclosure  was
   made.  A stockholder's notice to the Secretary shall set forth as  to
   each matter  the stockholder  proposes to  bring before  the  meeting
   (a) a brief description of the business desires to be brought  before
   the meeting  and the  reasons for  conducting  such business  at  the
   meeting,  (b) the  name   and  address,   as  they   appear  on   the
   corporation's books,  of  the stockholder  proposing  such  business,
   (c) the class  and number  of shares  of  the corporation  which  are
   beneficially owned by the  stockholder and (d) any material  interest
   of the stockholder in such business.  Notwithstanding anything in the
   By-Laws to  the  contrary,  no  business  shall  be  conducted  at  a
   stockholder meeting  except in  accordance  with the  procedures  set
   forth in this Section 10.  The Chairman of the meeting shall, if  the
   facts warrant, determine and declare to the meeting that business was
   not properly brought before  the meeting and  in accordance with  the
   provisions of the By-Laws,  and if the  Chairman should so  determine
   and declare to the  meeting, any such  business not properly  brought
   before the  meeting shall  not be  transacted.   Notwithstanding  the
   foregoing provision  of this  Section 10,  a stockholder  shall  also
   comply with all  applicable requirements of  the Securities  Exchange
   Act of 1934,  as amended, and  the rules  and regulations  thereunder
   with respect to  the matters  set forth in  this Section  and in  the
   event of any conflict with any  such applicable requirements and  the
   foregoing provisions of this Section 10, such applicable requirements
   shall prevail.

<PAGE>
                    ARTICLE I - BOARD OF DIRECTORS

   Section 1.  Number and Term of Office

        The number of  directors who  shall constitute  the whole  board
   shall be such number not less than  four nor more than twenty as  the
   Board of Directors shall at the time have designated.  Each  director
   shall be elected for a  term of one year  and until his successor  is
   elected  and  qualified,  except  as  otherwise  provided  herein  or
   required by law.

        Whenever the authorized number of directors is increased between
   annual meetings of the stockholders, a majority of the directors then
   in office shall have  the power to elect  such new directors for  the
   balance of  a  term  and  until  their  successors  are  elected  and
   qualified.  Any decrease in the authorized number of directors  shall
   not become  effective  until  the  expiration  of  the  term  of  the
   directors then in office unless, at the time of such decrease,  there
   shall be vacancies  on the board  which are being  eliminated by  the
   decrease.

   Section 2.  Vacancies

        If the office of any director becomes vacant by reason of death,
   resignation, disqualification, removal, or other cause, a majority of
   the directors remaining in office, although  less than a quorum,  may
   elect a successor for the unexpired  term and until his successor  is
   elected and qualified.

   Section 3.  Regular Meetings

        Regular meetings of the Board of Directors shall be held at such
   place or places, on such date or dates, and at such time or times  as
   shall have been established by the Board of Directors and  publicized
   among all directors.  A notice  of each regular meeting shall not  be
   required.

   Section 4.  Special Meetings

        Special meetings of the Board of Directors may be called by one-
   third of  the directors  then in  office or  by the  Chief  Executive
   Officer and shall be held  at such place, on  such date, and at  such
   time as they or he shall fix.  Notice of the place, date, and time of
   each such special meeting shall be given each director by whom it  is
   not waived by mailing written notice not less than three days  before
   the meeting or by telegraphing the same not less than eighteen  hours
   before the  meeting.    Unless  otherwise  indicated  in  the  notice
   thereof, any and all business may be transacted at a special meeting.

   Section 5.  Quorum

        At any meeting of the Board of Directors, one-third of the total
   number of the whole board, but not less than two, shall constitute  a
   quorum for  all purposes.   If  a  quorum shall  fail to  attend  any
   meeting, a  majority of  those present  may  adjourn the  meeting  to
   another place,  date,  or  time  without  further  notice  or  waiver
   thereof.
<PAGE>
   Section 6.  Participation in Meetings by Conference Telephone

        Members of the Board of Directors, or of any committee  thereof,
   may participate in a meeting of  such board or committee by means  of
   conference telephone or similar communications equipment that enables
   all persons participating in  the meeting to hear  each other.   Such
   participation shall constitute presence in person at such meeting.

   Section 7.  Conduct of Business

        At any  meeting of  the Board  of Directors,  business shall  be
   transacted in such  order and manner  as the board  may from time  to
   time determine, and all matters shall be determined by the vote of  a
   majority of  the  directors  present, except  as  otherwise  provided
   herein or required  by law.   Action  may be  taken by  the Board  of
   Directors without a meeting if all members thereof consent thereto in
   writing, and the writing  or writings are filed  with the minutes  of
   proceedings of the Board of Directors.

   Section 8.  Powers

        The Board of Directors may, except as otherwise required by law,
   exercise all such powers and  do all such acts  and things as may  be
   exercised or done by the corporation, including, without limiting the
   generality of the foregoing, the unqualified power:

        (1)  To declare dividends from time  to time in accordance  with
   law;

        (2)  To purchase or  otherwise acquire any  property, rights  or
   privileges on such terms as it shall determine;

        (3)  To authorize  the creation,  making and  issuance, in  such
   form as  it may  determine, of  written  obligations of  every  kind,
   negotiable or non-negotiable,  secured or  unsecured, and  to do  all
   things necessary in connection therewith;

        (4)  To remove any  officer of the  corporation with or  without
   cause and, from time to time, to devolve the powers and duties of any
   officer upon any other person for the time being;

        (5)  To confer upon any officer of the corporation the power  to
   appoint, remove and suspend subordinate officers and agents;

        (6)  To adopt  from  time  to  time  such  stock  option,  stock
   purchase, bonus, or other compensation plans for directors,  officers
   and agents  of  the  corporation  and  its  subsidiaries  as  it  may
   determine;

        (7)  To adopt from time to time such insurance, retirement,  and
   other benefit  plans  for  directors,  officers  and  agents  of  the
   corporation and its subsidiaries as it may determine; and

        (8)  To adopt from  time to time  regulations, not  inconsistent
   with these by-laws, for the management of the corporation's  business
   and affairs.
<PAGE>
   Section 9.  Compensation of Directors

        Directors, as such, may receive,  pursuant to resolution of  the
   Board of  Directors,  fixed fees  and  other compensation  for  their
   services as directors, including, without limitation, their  services
   as members of committees of the directors.


                        ARTICLE II - COMMITTEES

   Section 1.  Committees of the Board of Directors

        The Board of  Directors, by a  vote of a  majority of the  whole
   board, may from time to time designate committees of the board,  with
   such lawfully-delegable powers and duties  as it thereby confers,  to
   serve at the pleasure  of the board and  shall, for those  committees
   and any others provided for herein, elect a director or directors  to
   serve as the  member or members,  designating, if  it desires,  other
   directors as  alternative  members  who may  replace  any  absent  or
   disqualified member at any meeting of  the committee.  Any  committee
   so designated may exercise  the power and authority  of the Board  of
   Directors to declare a dividend or to authorize the issuance of stock
   if the resolution  which designates the  committee or a  supplemental
   resolution of  the Board  of  Directors shall  so  provide.   In  the
   absence or disqualification of  any member of  any committee and  any
   alternate member in his place, the member or members of the committee
   present at the meeting and not  disqualified from voting, whether  or
   not he or  they constitute a  quorum, may by  unanimous vote  appoint
   another member of the Board of Directors to act at the meeting in the
   place of the absent or disqualified member.

   Section 2.  Conduct of Business

        Each committee may  determine the procedural  rules for  meeting
   and conducting its  business and shall  act in accordance  therewith,
   except as otherwise  provided herein or  required by  law.   Adequate
   provision shall be made for notice  to members of all meetings;  one-
   third of the members shall constitute  a quorum unless the  committee
   shall consist of one or two members, in which event one member  shall
   constitute a  quorum;  and  all matters  shall  be  determined  by  a
   majority vote of  the members present.   Action may  be taken by  any
   committee without a meeting if all members thereof consent thereto in
   writing, and the writing  or writings are filed  with the minutes  of

   Section 1.  Right to Indemnification

        The corporation  shall  indemnify  and  hold  harmless,  to  the
   fullest extent permitted by applicable law as it presently exists  or
   may hereafter be amended, any person (an "Indemnitee") who was or  is
   made or is threatened to be made a party or is otherwise involved  in
   any  action,   suit   or   proceeding,   whether   civil,   criminal,
   administrative or investigative  (a "proceeding"), by  reason of  the
   fact that he, or a person for whom he is the legal representative, is
   or was a director or officer of the corporation or, while a  director
   or officer  of the  corporation, is  or was  serving at  the  written
   request of the corporation as a director, officer, employee or  agent
   of another corporation  or of  a partnership,  joint venture,  trust,
   enterprise or  nonprofit entity,  including service  with respect  to
   employee benefit plans, against all  liability and loss suffered  and
   expenses (including  attorneys'  fees) reasonably  incurred  by  such
   Indemnitee.    Notwithstanding  the  preceding  sentence,  except  as
   otherwise provided in Section  3 of this  Article V, the  corporation
   shall be required  to indemnify an  Indemnitee in  connection with  a
   proceeding (or part thereof) commenced by such Indemnitee only if the
   commencement of such proceeding (or  part thereof) by the  Indemnitee
   was authorized by the Board of Directors.

   Section 2.  Prepayment of Expenses

        The corporation  shall pay  the expenses  (including  attorneys'
   fees) incurred  by  an  Indemnitee in  defending  any  proceeding  in
   advance of  its  final  disposition,  provided,  however,  that  such
   payment of  expenses  in advance  of  the final  disposition  of  the
   proceeding shall be made only upon  receipt of an undertaking by  the
   Indemnitee to repay all amounts advanced  if it should be  ultimately
   determined that  the Indemnitee  is not  entitled to  be  indemnified
   under this Article V or otherwise.

   Section 3.  Claims

        If a claim for indemnification or advancement of expenses  under
   this Article V is  not paid in  full within sixty  (60) days after  a
   written claim therefor  by the Indemnitee  has been  received by  the
   corporation, the  Indemnitee  may file  suit  to recover  the  unpaid
   amount of such claim and, if successful in whole or in part, shall be
   entitled to be paid  the expense of prosecuting  such claim.  In  any
   such action the corporation shall have the burden of proving that the
   Indemnitee is  not  entitled  to  the  requested  indemnification  or
   advancement of expenses under applicable law.

   Section 4.  Nonexclusivity of Rights

        The rights conferred on any Indemnitee  by this Article V  shall
   not be exclusive of any other  rights which such Indemnitee may  have
   or hereafter acquire under any statute, provision of the  certificate
   of incorporation, these by-laws,  agreement, vote of stockholders  or
   disinterested directors or otherwise.

   director,  officer,  employee  or   agent  of  another   corporation,
   partnership, joint  venture, trust,  enterprise or  nonprofit  entity
   shall be  reduced  by  any amount  such  Indemnitee  may  collect  as
   indemnification  or   advancement  of   expenses  from   such   other
   corporation, partnership, joint  venture, trust,  enterprise or  non-
   profit enterprise.

   Section 6.  Amendment or Repeal

        Any repeal or modification of  the foregoing provisions of  this
   Article  V  shall  not  adversely  affect  any  right  or  protection
   hereunder of  any  Indemnitee  in respect  of  any  act  or  omission
   occurring prior to the time of such repeal or modification.

   Section 7.  Other Indemnification and Prepayment of Expenses

        This Article V shall not limit the right of the corporation,  to
   the extent and in  the manner permitted by  law, to indemnify and  to
   advance expenses  to  persons  other than  Indemnitees  when  and  as
   authorized by appropriate corporate action.

   prior to the time for the  other action hereinafter described, as  of
   which there shall be determined the stockholders who are entitled  to
   notice  of  or  to  vote  at  any  meeting  of  stockholders  or  any
   adjournment thereof;  to  express  consent  to  corporate  action  in
   writing without  a meeting;  to receive  payment of  any dividend  or
   other distribution or  allotment of any  rights; or  to exercise  any
   rights with respect to any change, conversion or exchange of stock or
   with respect to any other lawful action.

   Section 4.  Lost, Stolen or Destroyed Certificates

        In  the  event  of  the  loss,  theft  or  destruction  of   any
   certificate of stock, another may be issued in its place pursuant  to
   such regulations as the Board  of Directors may establish  concerning
   proof of such loss, theft or destruction and concerning the giving of
   a satisfactory bond or bonds of indemnity.

   Section 5.  Regulations

        The   issue,   transfer,   conversion,   and   registration   of
   certificates of stock shall be governed by such other regulations  as
   the Board of Directors may establish.

   Section 1.  Notices

        Whenever notice  is required  to be  given to  any  stockholder,
   director, officer, or agent, such requirement shall not be  construed
   to mean  personal notice.    Such notice  may  in every  instance  be
   effectively given by depositing a writing in a post office or  letter
   box in  a  postpaid, sealed  wrapper,  or by  dispatching  a  prepaid
   telegram, addressed to such stockholder, director, officer, or  agent
   at his  or her  address as  the  same appears  on  the books  of  the
   corporation.  The time  when such notice is  dispatched shall be  the
   time of the giving of the notice.

   Section 2.  Waivers

        A written  waiver  of  any  notice,  signed  by  a  stockholder,
   director, officer or agent, whether before  or after the time of  the
   event for which notice is to be given, shall be deemed equivalent  to
   the notice  required  to  be given  to  such  stockholder,  director,
   officer or  agent.   Neither  the business  nor  the purpose  of  any
   meeting need be specified in such a waiver.

      enlarge or extend the limit.


   ARTICLE IX:  CONFIDENTIAL INFORMATION
      9.1. "Confidential Information" shall mean (a) any  information
      conveyed in written, graphic, machine-readable or other tangible
      form, provided that such information is conspicuously marked
      and/or considered by a party as confidential or proprietary; or
      (b) any information conveyed orally where such information is
      designated as confidential or proprietary at the time of such
      oral disclosure.  Notwithstanding the above, information shall
      not be deemed Confidential Information to the extent that it
      (i) was generally known and available in the public domain at the
      time it was disclosed or subsequently becomes generally known and
      available in the public domain through no fault of the recipient;
      (ii) was known to the recipient at the time of disclosure;
      (iii) is disclosed with the prior written approval of the
      disclosing party; (iv) was independently developed by the
      recipient without any use of the Confidential Information of the
      disclosing party; or (v) becomes known to the recipient from a
      source other than the disclosing party without breach of this
      Agreement.The obligation not to use or disclose said Confidential
      Information will remain in effect until one of these exceptions
      occurs.

<PAGE>
   9.2. Both  parties  agree  not  to  disclose  any  trade  secrets  or
      Confidential  Information transferred  to it  by the  other  party
      which are identified  in writing and/or are considered by a  party
      as   confidential.   Each   party  shall   protect   the   other's
      Confidential Information  form unauthorized dissemination and  use
      with the same  degree of care that such party uses to protect  its
      own  like   information.  Neither  party  will  use  the   other's
      Confidential  Information for  purposes  other than  necessary  to
      directly  further the purposes  of this  Agreement. Neither  party
      will   disclose  to   third  parties   the  other's   Confidential
      Information without the prior written consent of the other  party.
      Except  as expressly provided in  this Agreement, no ownership  or
      license rights are granted in any Confidential information.

   9.3. Since  unauthorized   transfer  of   one  party's   Confidential
      Information  will substantially  diminish their  value and  injure
      that  party in ways that  cannot be remedied  fully by money,  the
      other party's breach of these Article IX obligations will  entitle
      first  party to equitable  relief (including  orders for  specific
      performance and injunctions), as well as monetary damages.

   9.4. Both parties  agree  that the  terms  and conditions,  and  this
      Agreement itself shall be considered as Confidential  Information,
      except as expressly otherwise stated in this Agreement.

                                ADDENDUM A

                     SOFTWARE FUNCTIONAL SPECIFICATION

   1. Functional Specification of the Development Software

   Speaker Verification

   Lernout & Hauspie has developed speaker  verification software for
   use in access  control applications.  The VOICE PRINT  software is
   built around  the L&H  speaker verification  engine.   As  such it
   allows for  seamless  integration  in  already existing  telephone
   applications.

   The actual scenario and  combination of different  elements in the
   verification  procedure  is  under  control   of  the  application
   developer. He can combine several attempts or several passwords to
   improve the overall security.

   PRODUCT DESCRIPTION
   
        Enrollment of a new speaker

   Each new  person  is  asked to  select  his  personal password  or
   passwords (each at  least 1  second in length)  and enter  3 times
   into  the  system.    The  verification  software  checks  if  the
   password(s)  is  (are) sufficiently long,  contains a sufficiently
   rich subset of phonemes and if the said utterances were consistent
   over the 3 enrollment utterances.  Out of each utterance a feature
   vector, or voice token, is extracted.  The 3 voice tokens are then
   combined by  the verification  engine into  a single  Voice Print,
   which is the  final representation  of the  identity of  the user.
   The whole enrollment procedure should not  take longer than half a
   minute.

          Verification Procedure

   This is a 2-step procedure.
   Identity Claim:  First the person needs to identify himself to the
   system.  This can  be achieved by  using `a token'  for entering a
   name or  access  number but  could  also be  achieved  by keyboard
   input, magnetic badge, or any other suitable method.
   VOICE PRINT verification: As primary verification check the person
   is asked  to enter  his  voice password.    A new  voice  token is
   extracted from  the uttered   sample  and is  matched  against the
   centrally stored voice print.
<PAGE>
          Features

        . passwords of 1 second or longer
        . consistency check during enrollment
        . utterance length control
        . tradeoff between false acceptance and false rejection by
          simple threshold control
        . possibility of integration of multiple identity claims and
          multiple verification prompts
        . environment: this product is designed to work over
          telephone input.
        . response time: less than 0.5 seconds

   PERFORMANCE
 
   Using a double voice print of  each 1 to 2 seconds long (3-4
   syllable word)  following average equal error rates have been
   obtained:
        .  better than 4% EER in case the intruder KNOWS the password

   Using a triple voice print of  each 1 to 2 seconds long (3-4
   syllable word)  following average equal error rates have been
   obtained:
        .  better than 3% EER in case the intruder KNOWS the password


   SYSTEM REQUIREMENTS

   Minimum 486 PC, equipped with the necessary telephony hardware and
   software, Windows '95, Minimum 8 MB RAM

   Background storage (on disk) of a voice print requires as little
   as 1.4kByte pre second of speech. An active keyword (in RAM)
   requires 25kByte/second.

   Client-Server architecture is supported

   2. Deliverables

        Licensee agrees having received he SDK for Speaker  verification
        and  the  software  supporting  logic  to  combine  scores  from
        individual trials  and multiple  passwords. And  furthermore  he
        hereby accepts the development software.



                                ADDENDUM B

                DESIGNATED APPLICATION/ LIMITED EXCLUSIVITY


      1.  Designated Application

      The  Run-Time Software  will be  incorporated into  the  following
      LICENSEE' s proprietary application(s):
<PAGE>
      Products into  which the Run-Time Software represents an  inherent
      part  of  its security  function,  or add-on  modules  to  certain
      products into  which the Run-Time Software represents an  inherent 
      part  of its security  function, which are  being deployed in  the
      field of:
      
      Telecom Applications.

      Data Security Applications

      Physical Access Applications.
      
      Future applications to be defined in mutual agreement.
     
      2.  LIMITED EXCLUSIVITY
      
      The  license granted under  article 2.1. shall  be exclusive  with
      respect to Data Security Applications under which LICENSOR's  Run-
      Time  Software is  used  as an  alternate method  to  authenticate
      users  under  LICENSEE'  s patents  4,599,489  Claim  1  (attached
      hereto  as Exhibit  1) and  0172239 Claim  1 (attached  hereto  as
      Exhibit  2), under the assumption  of LICENSEE' s  representations
      and  warranties that it  fully and solely  owns the above  patents
      and  that these  patents have not  been invalidated  by any  third
      party.

      Both patents  describe the use of a device that is analogous to  a
      key   to  generate   passwords  for   authenticating  users.   The
      exclusivity  pertains to  Data Security  Applications under  which
      the  users are required to generate a  voice sample that can  then
      be  transmitted to the  computer for verification  using the  Run-
      Time  Software, all in  accordance with and  limited to the  above
      claims under the above mentioned patents.

      LICENSEE  acknowledges that LICENSOR  retains the  right to  enter
      into  agreements, without any restriction or consideration,  under
      which its customers, either existing or new, shall have the  right
      to  commercially   use  and  exploit  the  Run-Time  Software   in
      connection  with  Data  Security  Applications  in  so  far   said
      applications do not infringe the above patents of LICENSEE.

      Furthermore, nothing  in this Agreement shall prevent LICENSOR  to
      license  the  Run-Time Software  to  its existing  customer  base,
      under which LICENSOR has sold or licensed an L&H product, as  well
      as to  customers who received a license from LICENSEE under  which
      such customer  is or will be allowed to practice the claims  under
      the above patents.
      
      This  exclusivity shall  commence on  the Effective  Date of  this
      Agreement and shall remain for a period of five(5) years,

      (i) so long as LICENSEE:
      a)     does not enter into  agreements with other speech  software
         companies;

      b)     makes timely payments to LICENSOR under this Agreement  and
         other agreements;
<PAGE>
      c)     remains the sole owner of the above patents;

      (ii) unless the patents are abandoned by LICENSEE or such  patents
      becomes the subject of a patent invalidation;

      (iii) provided  both parties evaluate from  time to time, but  not
      less  than once  a year,  the revenue  forecasts to  be  generated
      under the exclusivity.
      
      The  failure to  achieve any  of the  above cumulative  conditions
      shall immediately revert the exclusivity into a non- exclusivity.
      
      In  addition,  both parties  agree  to  consider the  other  as  a
      Strategic  Partner. As such,  both parties agree  to negotiate  in
      good  faith to issue  a license(s) to  companies in Data  Security

                              ROYALTY PRICING
      
   1. Royalties

      a) The royalty to  be paid by LICENSEE  for the use of  LICENSOR's
         Run-Time Software  consists   of  ten  percent (10  %)  of  the
         revenue of LICENSEE related to the Designated Applications.

      b)     LICENSEE hereby commits to a non-refundable pre-payment  on
         royalties  in  the  amount  of  US  $  800.000  (eight  hundred
         thousand US $).

      c) LICENSEE will provide LICENSOR with calendar quarterly  reports
         showing  the  quantity   of  royalty-bearing   copies  of   the
         Designated Application  shipped and/or  distributed  hereunder,
         commencing three  (3) months  after the  Effective Date.  These
         quarterly reports  shall  be provided  to LICENSOR  within  ten
         (10) days after each quarter.  LICENSEE shall at the same  time
         transfer  the  amount  of  royalties  due  to  LICENSOR's  bank
         account for all such royalties due.

      d) LICENSEE shall  keep  a separate  register  in which  it  shall
         record the exact number of royalty- bearing copies, as well  as
         the type of the  Designated Application incorporating the  Run-
         Time  Software   and  any   other  information   relevant   for
         determining the amounts of royalties payable.

         LICENSOR shall have the right to conduct an audit of  LICENSEE,
         and (through LICENSEE), Third  Parties records relative to  the
         performance of this Agreement no  more than once yearly.   Such
         audit shall  be  conducted by  a mutually  acceptable  auditing
         firm, independent from the parties.

         LICENSEE's  approval of  the  time  and  place  for  the  audit
         requested by LICENSOR shall not be unreasonably withheld.
<PAGE>
         Any audit shall be performed  during normal business hours.  In
         the event  such  audit  reveals an  underpayment  to  LICENSOR,
         LICENSEE shall  pay LICENSOR  such underpayment  within  thirty
         (30) days, as well as the audit costs. Those audit costs  shall
         only be paid  by LICENSEE if the  underpayment is greater  than
         five percent (5%).
     
   2. Engineering Fees

      No  engineering specification  is  currently anticipated.  In  the
      event  engineering needs to be  performed, a separate  engineering
      agreement will be executed.
  
   3. Payment Terms

   a) LICENSEE will pay a first non-refundable pre-payment on  royalties
      to  the amount of six hundred thousand US Dollars ($ 600,000  USD)
      within  three  (3)  months  after  the  Effective  Date  of   this
      Agreement.    This  non-refundable  prepayment  will  be  credited
      against royalty payments as described in this Agreement.  LICENSEE
      shall  pay the non-refundable prepayment according to the  payment
      schedule as mentioned hereunder:

      LICENSEE   will  pay  a   second  non-refundable  pre-payment   on
      royalties  to the  amount of two  hundred thousand  US Dollars  ($
      200,000  USD) within twelve (12)  months after the Effective  Date
      of  this  Agreement.    This  non-refundable  prepayment  will  be
      credited against royalty payments as described in this  Agreement.
      LICENSEE shall pay the non-refundable prepayment according to  the
      payment schedule as mentioned hereunder:
      
        After the minimum committed royalties, the amounts of royalties
        shall be paid by LICENSEE to LICENSOR in quarterly basis and
        shall be calculated according to section 1 of this Addendum,
        being it understood that during the commitment period, or any
        extension thereof, royalties shall be at least equal to or be
        higher than the minimum amounts as specified in section 3.a).

        This means that if during the commitment period/or any extension
        thereof, the royalty fee in a specific quarter would be less
        than the corresponding minimum amount to be paid in such
        quarters, LICENSEE shall pay the minimum amount, but shall be
        entitled to offset the difference in and against any future
        quarterly royalty payments, which would exceed the corresponding
        minimum amounts, provided however that such offset shall be
        limited each quarter to the amount paid in excess of the
        corresponding minimum amount.

        Any royalties due for a  specific quarter under this  agreement,
        upon consummation of  the committed quantity,  shall be paid  by
        LICENSEE no  later than  ten (10)  days after  the end  of  such
        specific quarter.

   b) Payment  of Non-Refundable Engineering  Fee will  be defined  when
      applicable.

   acknowledged, the Borrower and Lender agree as follows.

        1.   CERTAIN DEFINITIONS.  As used herein the terms set forth on
   Schedule I hereto shall have the meanings set forth thereon.

        2.   THE LOAN.

        (a)  At any time after  the date hereof  through April 30,  1998

   transfer fees and  the like) incurred  by Lender  in connection  with
   such advance  methods, except  for an  advance by  bank or  certified
   check).

        3.   REPRESENTATIONS AND WARRANTIES.

        The Borrower hereby represents and warrants to the Lender that:
<PAGE>
        (a)  Organization  and  Qualification.     The  Borrower  is   a
   corporation duly  organized, validly  existing and  in good  standing
   under the laws of the jurisdiction  of its incorporation and has  all
   required corporate power and authority to own its property, to  carry
   on  its  business  as  presently  conducted  and  to  carry  out  the
   transactions contemplated hereby.

        (c)  Capitalization.    The  authorized  capital  stock  of  the
   Borrower consists of  75,000,000 shares  of common  stock, $.001  par
   value ("Common Stock") of which 20,316,585 shares are validly  issued
   and outstanding, fully paid and non-assessable.  Except as  disclosed
   in the Prospectus  attached hereto  as Exhibit  C, (a)  there are  no
   outstanding warrants, options, preemptive  rights or other rights  to
   purchase or acquire, or any agreements providing for the issuance  or
   sale of (contingent or  otherwise), or any  commitments or claims  of
   any character relating to, any of the Borrower's capital stock or any
   shares of stock  or securities convertible  into or exchangeable  for
   any such  capital stock,  and  (b) there  are  no securities  of  the
   Borrower convertible into or exchangeable for shares of capital stock
   of the  Borrower.   Except as  disclosed in  the Prospectus  attached
   hereto as Exhibit C, there are no restrictions on the transfer of the
   Borrower's capital  stock, other  than  those imposed  by  applicable
   federal and state securities laws.

        (d)  Authorization of Transaction.  The execution, delivery  and
   performance of  this  Agreement  have been  duly  authorized  by  all
   necessary corporate or  other action of  the Borrower and  it is  the
   valid  and  binding  obligation  of  the  Borrower,  enforceable   in
   accordance with its  terms, subject  to laws  of general  application
   relating to bankruptcy, insolvency  and the relief  of debtors.   The
   issuance of the Note pursuant to the terms of this Agreement is  duly
   and validly authorized, and no further  approval or authority of  the
   shareholders or the directors of the Borrower or of any  governmental
   authority or agency will be required for the issuance and sale of the
   Note as contemplated by this Agreement.

        (e)  Approvals; Compliance With Laws.   The execution,  delivery
   and performance of this  Agreement and the transactions  contemplated
   hereby (i) do not require any approval or consent of, or filing with,
   any governmental agency or authority in the United States of  America
   or otherwise which  has not been  obtained and which  is not in  full
   force and effect as of the  date hereof, (ii) will not conflict  with
   or constitute a breach or violation of the Charter or By-laws of  the
   Borrower, and (iii) will not result in  a violation of or any law  or
   regulation to which it is subject.
<PAGE>
        (f)  Disclosure.   Neither  this Agreement,  together  with  any
   financial statement, schedule, exhibit,  or other statement  (written
   or oral) pertaining to the Borrower, made, delivered or  communicated
   to the  Lender  by the  Borrower  or any  representative  thereof  in
   connection with this Agreement and the transactions related  thereto,
   contains any untrue statement  of a material fact  or omits to  state
   any material fact necessary in order to make the statements contained
   therein not misleading in light of the circumstances under which they
   were made.

        4.   BORROWER'S AGREEMENTS.  The Borrower agrees as follows:

        (a)  Borrower will  notify Lender,  at  least thirty  (30)  days
   prior to any  such event,  of any  change in  Borrower's exact  legal
   name, any change in its place of business or location as set forth in
   the preamble to this Agreement, or its establishment of any new place
   of business or location, or  any change in Borrower's  organizational
   structure.

        (b)  The Borrower will deliver to the Lender until such time  as
   the Borrower becomes a reporting Borrower  under the Exchange Act  of
   1934, as amended (the "Exchange Act"), such financial statements  and
   other information as the Borrower may  provide to any other  security
   holder or lender to the Borrower; and (b) with reasonable promptness,
   such other  financial  data  related to  the  business,  affairs  and
   financial condition  of  the  Borrower and  any  subsidiaries  as  is
   available to the  Borrower and as  from time to  time the Lender  may
   reasonably request.

        (c)  Except as consented  to by the  Lender, the Borrower  shall
   not pay or  set apart for  payment to holders  of capital stock,  any
   dividends, and the Borrower shall not  redeem or purchase any  shares
   of capital stock.

        (d)  The Borrower may not  amend the Charter  or By-laws of  the
   Borrower in such a manner as  may adversely affect the rights of  the
   Lender hereunder,  the Note  or  any Common  Stock  to be  issued  in
   connection herewith or therewith.

        (e)  The Borrower will permit representatives designated by  the
   Lender, at its expense, to visit and inspect any of the properties of
   the Borrower (or any subsidiary), and to inspect and make extracts of
   the books and records  of the Borrower, and  to discuss the  affairs,
   finances, and accounts of the Borrower with its officers, all to such
   reasonable extent and at such reasonable  times and intervals as  the
   representatives may reasonably request.   If the Borrower  determines
   that such inspection might result in the disclosure of trade  secrets
   or other  confidential information,  the  Borrower may  require  such
   persons to sign nondisclosure agreements with respect thereto.
<PAGE>
        (f)  The  Borrower  will   maintain  and  cause   each  of   its
   subsidiaries now in existence or  hereinafter acquired or created  to
   maintain its corporate existence in good standing and comply with all
   applicable laws and regulations of the United States or of any  state
   or states thereof or of any political subdivisions thereof or of  any
   government authority,  where  failure  to  so  comply  would  have  a
   material adverse effect on the  Borrower and its subsidiaries,  taken
   as a whole; provided, however, that nothing herein shall prohibit the
   Borrower from liquidating or dissolving any of its subsidiaries  into
   the Borrower or  merging any  of its  subsidiaries with  or into  the
   Borrower or any other Subsidiary.

        (g)  The  Lenders  shall  have  such  registration  rights  with
   respect to  the  shares of  Common  Stock  as may  be  issuable  upon
   conversion  of  the  Note,  as  are   no  less  favorable  than   any
   registration rights  granted  to  any  other  securityholder  of  the
   Borrower, whether now or hereafter existing.

        5.   CONVERSION.

        (a)  Conversion Right.   Subject to and  in compliance with  the
   provisions of this Section 5, all or any part of the principal amount
   and unpaid interest outstanding under the Note may, at the option  of
   the holder thereof,  be converted at  any time or  from time to  time
   into fully-paid  and non-assessable  shares of  Common Stock  of  the
   Borrower.

        (b)  Applicable Conversion  Value.   Subject  to  adjustment  as
   hereinafter provided, the number of shares of Common Stock into which
   the Note may be converted shall be equal to (i) the aggregate  amount
   of principal and unpaid  interest outstanding under  the Note on  the
   Conversion Date (as defined below) divided by (ii) the average of the
   high and low bid and ask prices for the Common Stock for the ten (10)
   consecutive trading  days immediately  preceding March  12, 1998,  or
   $5.6813 per share.

        (c)  Adjustment for Dividends; Reclassification,  etc.  In  case
   at any time or from time to  time after the date hereof, the  holders
   of Common Stock (or other capital  stock of the Borrower) shall  have
   received, or (on or after the record date fixed for the determination
   of shareholders eligible  to receive) shall  have become entitled  to
   receive, without payment  therefor (i) other  or additional stock  or
   other securities or property (including cash)  by way of dividend  or
   (ii) other  or  additional  stock or  other  securities  or  property
   (including cash)  by  way of  spin-off,  split-up,  reclassification,
   recapitalization,  combination   of  shares   or  similar   corporate
   rearrangement, then and in each such case the holder of the Note,  on
   the conversion  thereof  as provided  in  this Section  5,  shall  be
   entitled to  receive the  amount of  stock and  other securities  and
   property (including cash) which such holder would hold on the date of
   such conversion  if on  the date  hereof he  had been  the holder  of
   record of  the  number  of  shares  of  Common  Stock  issuable  upon
   conversion of the Note and had thereafter, during the period from the
   date hereof to and  including the date  of such conversion,  retained
   such shares  and  all  such  other  or  additional  stock  and  other
   securities  and  property  (including  cash)  receivable  thereby  as
   aforesaid during such period, giving effect to all adjustments called
   for during such period under this Section 5.
<PAGE>
        (d)  Adjustment for Reorganization, Consolidation, Merger,  etc.
   In case at  any time or  from time to  time, the  Borrower shall  (i)
   effect a reorganization,  (ii) consolidate  with or  merger into  any
   other person or entity, or (iii) transfer all or substantially all of
   its properties or assets to any other person or entity under any plan
   or arrangement contemplating the  dissolution of the Borrower,  then,
   in each such case, the holder of the Note, on the conversion  thereof
   as provided in this Section 5  at any time after the consummation  of
   such reorganization, consolidation or merger or the effective date of
   such dissolution, as the case may  be, shall receive, in lieu of  the
   Common Stock issuable on such exercise prior to such consummation  or
   such effective  date,  the stock  or  other securities  and  property
   (including cash) to which such holder  would have been entitled  upon
   such consummation or in connection with such transaction, as the case
   may be, if such holder had  so converted its Note, immediately  prior
   thereto, all  subject to  further adjustment  thereafter as  provided
   under this Section 5.

        (e)  Continuation  of   Terms.      Upon   any   reorganization,
   consolidation, merger or transfer (and any dissolution following  any
   transfer) referred  to  in  paragraph  (d)  above,  each  Note  shall
   continue in  full force  and effect  and the  terms hereof  shall  be
   applicable to the shares of stock  and other securities and  property
   receivable on the conversion  of the Note  after the consummation  of
   such reorganization, consolidation or merger or the effective date of
   dissolution following  any such  transfer, as  the case  may be,  and
   shall be  binding  upon  the  issuer  of  any  such  stock  or  other
   securities, including, in the case of  any such transfer, the  person
   or entity acquiring  all or substantially  all of  the properties  or
   assets of the Borrower.

        (f)  Exercise  of  Conversion  Privilege.     To  exercise   its
   conversion privilege, the  holder of  the Note  shall surrender  such
   Note being converted  to the Borrower  at its  principal office,  and
   shall give written notice  to the Borrower at  that office that  such
   holder elects to convert such Note,  or a portion thereof.  The  date
   when such written notice is received  by the Borrower, together  with
   the Note  being  converted,  shall be  the  "Conversion  Date."    As
   promptly as practicable after the Conversion Date, the Borrower shall
   issue and shall deliver to the holder of the Note being converted, or
   on its  written order,  such certificate  or certificates  as it  may
   request for  the number  of shares  of Common  Stock, as  applicable,
   issuable upon  the conversion  of such  Note in  accordance with  the
   provisions of this Agreement.

        (g)  Reservation of Common  Stock.   The Borrower  shall at  all
   times reserve and keep available out  of its authorized but  unissued
   shares of  Common Stock,  solely for  the  purpose of  effecting  the
   conversion of the Note, such number of its shares of Common Stock  as
   shall from time to time be sufficient to effect the conversion of all
   outstanding Note and  if at  any time  the number  of authorized  but
   unissued shares of Common Stock shall not be sufficient to effect the
   conversion of  all then  outstanding, the  Borrower shall  take  such
   corporate action as may be necessary  to increase its authorized  but
   unissued shares of Common Stock to such number of shares as shall  be
   sufficient for such purpose.
<PAGE>
        (h)  No Dilution  or  Impairment.   The  Borrower will  not,  by
   amendment of its Charter or  through any reorganization, transfer  of
   assets,  consolidation,  merger,  dissolution,   issue  or  sale   of
   securities or any other voluntary action, avoid or seek to avoid  the
   observance or performance of any of  the terms of the Note, but  will
   at all times in  good faith assist  in the carrying  out of all  such
   terms and in the  taking of all  such action as  may be necessary  or
   appropriate in order to protect the  rights of the holders of  shares
   of Common Stock issuable upon conversion of the Note against dilution
   or  other  impairment.    Without  limiting  the  generality  of  the
   foregoing, the Borrower (a)  will not increase the  par value of  any
   shares of stock receivable  on the conversion of  the Note above  the
   amount payable therefor on  such conversion, (b)  will take all  such
   action as may be necessary or appropriate in order that the  Borrower
   may validly and legally issue fully paid and nonassessable shares  of
   stock on the conversion  of all Note from  time to time  outstanding,
   (c) will not transfer all or substantially all of its properties  and
   assets to any other  person or entity, or  consolidate with or  merge
   into any other person or entity  or permit any such person or  entity
   to consolidate with or  merge into the Borrower  (if the Borrower  is
   not the surviving person), unless such  other person or entity  shall
   expressly assume in writing and will be bound by all the terms of the
   Note.

        6.   EVENTS OF  DEFAULT;  REMEDIES.   Upon  the  occurrence  and
   during the continuance of an Event of Default (as defined on Schedule
   I hereto), (a) the  Borrower shall have no  further right to  request
   the Loan hereunder, (b) the Loan  shall bear interest at the  Default
   Rate of  Interest, as  defined in  the Note,  (c) the  Lender may  by
   notice to Borrower accelerate the payment  of the Loan and all  other

   FOR   VALUE   RECEIVED,   the   undersigned   VASCO   DATA   SECURITY
   INTERNATIONAL,  INC.,  a   Delaware  corporation  ("Maker"),   hereby
   promises to pay  to the order  of LERNOUT &  HAUSPIE SPEECH  PRODUCTS
   N.V., a  Belgian  corporation, at  its  place of  business  at  Sint-
   Krispijnstraat 7, 8900  Ieper, Belgium ("Lender"),  the sum of  THREE
   MILLION DOLLARS ($3,000,000.00), or so much as may have been advanced
   to Maker  as  provided in  that  certain Loan  Agreement  (the  "Loan
   Agreement") dated  as of  March 31,  1998 between  Maker and  Lender,
   together with interest on  the unpaid principal  amount from time  to
   time outstanding prior to demand at  a fixed rate per annum equal  to
   one percent (1%) over the Prime Rate in effect as of the date hereof.

   Prior to the  occurrence of an  Event of Default,  as defined in  the
   Loan Agreement,  interest shall  be payable  quarterly on  the  first
   business day of each of July and October.  All outstanding  principal
   and interest shall be due and payable in full on January 4, 1999.

   After the  occurrence  and during  the  continuance of  an  Event  of
   Default, (a) principal outstanding hereunder shall bear interest at a
   fixed rate equal to  the sum of the  Prime Rate in  effect as of  the
   date hereof plus four  percent (4%) per annum  (the "Default Rate  of
   Interest"), and (b) the  Lender shall be  entitled to accelerate  all
   outstanding principal and interest due hereunder and demand immediate
   payment in full of the same.

   Interest payable under  this Note is  subject to Belgian  withholding
   tax, at  a rate  of 15%  as of  the  date hereof.   Each  payment  of
   interest hereunder shall be increased by an amount equal to  one-half
   of the withholding tax obligation of the Lender with respect to  such
   payment.

   This Note is  convertible at  the option  of the  holder hereof  into
   shares of Common Stock of  the Maker in the  manner set forth in  the
   Loan Agreement.

   Interest and fees shall be calculated on the basis of a 360-day  year
   times the  actual number  of days  elapsed.   "Prime Rate,"  as  used
   herein, shall mean for any day the highest "prime rate" published  in
   The Wall Street Journal under the  heading "Money Rates" on such  day
   (or on the next day on  which The Wall Street Journal is  published).
   In no event shall interest payable hereunder exceed the highest  rate
   permitted by applicable law.  To the extent any interest received  by
   Lender exceeds the  maximum amount permitted,  such payment shall  be
   credited to principal, and any excess remaining after full payment of
   principal shall be refunded to Maker.  This Note evidences borrowings
   under the  Loan Agreement  and  is secured  by  and entitled  to  the
   benefits of  the  provisions of  the  Loan Agreement  and  any  other
<PAGE>
   instruments or  documents  executed  in connection  therewith.    The
   principal of this Note is subject to prepayment in full or in part at
   any time without  premium or penalty;  provided, however, that  Maker
   shall give  Lender at  least five  (5)  business days  prior  written
   notice of any prepayment to permit Lender to exercise its  conversion
   rights as provided in the Loan Agreement prior to such repayment.

   Maker and  all guarantors  and  endorsers hereby  waive  presentment,
   demand, notice,  protest,  and  all  other  demands  and  notices  in
   connection with the delivery, acceptance, performance and enforcement
   of this Note,  and assent  to extensions of  the time  of payment  or
   forbearance or other indulgence without notice.  No delay or omission
   of  Lender  in  exercising  any  right  or  remedy  hereunder   shall
   constitute a  waiver of  any such  right or  remedy.   Acceptance  by
   Lender of any payment  after demand shall not  be deemed a waiver  of
   such demand.  A waiver on one occasion shall not operate as a bar  to
   or waiver of any such right or remedy on any future occasion.

   Executed as  an instrument  under seal  as of  the date  first  above

                            SECURITY AGREEMENT

       SECURITY AGREEMENT  made by  VASCO DATA  SECURITY  INTERNATIONAL,
   INC. (the "Debtor") in favor of LERNOUT & HAUSPIE SPEECH PRODUCTS  N.
   V. (the  "Secured Party").   In  consideration  of the  agreement  of
   Secured Party to extend credit  or other financial accommodations  to
   the Debtor,  and  for  other good  and  valuable  consideration,  the
   receipt and sufficiency of which are hereby acknowledged, the  Debtor
   hereby agrees for the benefit of Secured Party as follows:

       1.  Grant of Security Interest.   As collateral security for  the
   payment and performance when due of the Obligations (defined  below),
   the Debtor  hereby collaterally  assigns, mortgages,  and pledges  to
   Secured Party, and hereby grants to Secured Party a security interest
   in, all of the  Debtor's right, title and  interest in, to and  under
   the Collateral (defined below).

        "Collateral" means all  the Debtor's present  and future  right,
        title and  interest in  and to  any of  the following  property,
        wherever located and  whether now owned  or hereafter  acquired:
        All of the Debtor's  tangible and intangible personal  property,
        including without limitation, all inventory, equipment and other
        goods, all  accounts  receivable,  notes,  drafts,  acceptances,
        instruments  and  documents,  contract  rights,  chattel  paper,
        general intangibles, deposit  accounts, books  and records,  and
        all cash and non-cash proceeds of the foregoing in whatever form
        received,  including  without  limitation  insurance   proceeds;
        provided, however, that Collateral shall not include patents  or
        other intellectual property.  Any  of the foregoing terms  which
        are specifically defined  in the Uniform  Commercial Code as  in
        effect in  the  Commonwealth  of Massachusetts  shall  have  the
        meanings given therein.

        "Obligations"  means  any  and   all  payment  and   performance
        obligations of  the Debtor  to Secured  Party, now  existing  or
        hereafter arising, direct or  indirect, absolute or  contingent, 
        due or  to become  due,  liquidated or  unliquidated,  including
        without limitation, Debtor's obligations to Secured Party  under
        that certain Loan  Agreement dated as  of the  date hereof  (the
        "Loan Agreement"), and that certain $3,000,000 Convertible  Note
        executed in connection therewith.

       2.  Secured Party's Rights and Obligations.  Debtor shall  remain
   liable under all accounts  receivable, instruments and documents  and
   general intangibles.  Secured Party shall not have any obligation  or
   liability under any accounts receivable, instruments and documents or
   general intangibles by  reason of this  Security Agreement nor  shall
   Secured  Party  be  required  to  perform  the  Debtor's  obligations
   pursuant thereto.  At any time, Secured Party shall have the right to
   verify accounts receivable constituting  a portion of the  Collateral
   and Debtor agrees to  cooperate with Secured  Party in arranging  for
   such verification.   After  an Event  of Default,  Secured Party  may
<PAGE>
   notify  account  debtors  that  the  accounts  receivable  have  been
   assigned to Secured Party and that payments shall be made directly to
   Secured Party.  At the request of Secured Party at any time after  an
   Event of Default,  the Debtor will  so notify  such account  debtors.
   Notwithstanding  any  such  action,  Secured  Party  shall  have   no
   obligation to inquire as to the  sufficiency of any payment  received
   by it or to take any action to collect or enforce the payment of  any
   account receivable.

       3.   Further Assurances.  Debtor will join with Secured Party  in
   executing such UCC financing statements as Secured Party may  request
   and will pay the cost of filing  the same in all public office  where
   filing is deemed necessary or desirable by Secured Party.  At Secured
   Party's request  from  time to  time,  the Debtor  will  execute  and
   deliver any and all such further  instruments and documents and  take
   such further actions as Secured  Party may reasonably deem  desirable
   in obtaining  the full  benefits of  this  Security Agreement.    The
   Debtor also hereby authorizes Secured Party  to execute on behalf  of
   the Debtor and  file UCC  financing or  continuation statements  with
   appropriate jurisdictions in order to perfect the security  interests
   granted herein.

       4.  Events of Default.  The occurrence of any Event of Default as
   defined in the Loan  Agreement shall constitute  an Event of  Default
   hereunder.

       5.  Remedies Upon Default.  If a Event of Default occurs, Secured
   Party may declare all Obligations secured hereby immediately due  and
   payable and shall have  all of the rights  and remedies of a  secured
   party under  the Uniform  Commercial Code  as now  in effect  in  the
   Commonwealth of Massachusetts or under other applicable law.  Without
   limitation, Secured  Party may  notify Debtor's  account or  contract
   debtors (or other  obligors whose obligations  to Debtor secure  this
   agreement) of Secured Party's security interest and that such account
   or contract debtors are to make  payments directly to Secured  Party.
   Secured Party may  send this notice  in Debtor's name  or in  Secured
   Party's name,  and at  Secured Party's  request Debtor  will join  in
   Secured Party's  notice,  provide  written  confirmation  of  Secured
   Party's security interest and request that payment be sent to Secured
   Party.   Secured  Party  may  enforce  this  obligation  by  specific
   performance.   Secured  Party may  collect  all amounts  due  on  the
   accounts and accounts  receivable.   Upon and  after notification  by
   Secured  Party  to  Debtor,  Debtor  shall  hold  any  proceeds   and
   collections of any of the collateral  in trust for Secured Party  and
   shall not commingle such  proceeds or collections  with any other  of
   Debtor's funds, and Debtor shall deliver all such proceeds to Secured
   Party immediately upon Debtor's receipt thereof in the identical form
   received and duly endorsed or assigned to Secured Party. At the
   request of  Secured Party,  the  Debtor shall  cause  the
   Collateral, or such portion  of the Collateral  as Secured Party  may
   direct,  to  be  assembled  for   Secured  Party  at  such   location
   (including, without limitation, Debtor's business address) as Secured
   Party may request.  Secured Party will give to the Debtor  reasonable
   notice of the time and place of  any public sale of Collateral or  of
   the time after which any private  sale or other intended  disposition
<PAGE>
   thereof is to be made.   Such requirement of reasonable notice  shall
   be met if such notice is mailed postage prepaid to the address of the
   Debtor set forth in this Agreement at least ten (10) days before  the
   time of the  proposed sale or  disposition.  Any  such sale may  take
   place from Debtor's location or such other location as Secured  Party
   may designate.   Debtor  shall remain  liable for  any deficiency  in
   payment of the Obligations after any such sale.

       Debtor hereby irrevocably appoints Secured Party as its true  and
   lawful attorney-in-fact with full power of substitution to take  such
   actions in the name of the Debtor  or Secured Party to carry out  the
   terms of this Agreement and to protect, enforce, preserve or  perfect
   Secured  Party's  rights  hereunder.    Such  power  of  attorney  is
   irrevocable and shall be deemed to be coupled with an interest.

       6.   Miscellaneous.  Expenses of enforcing Secured Party's rights
   hereunder including,  but  not  limited  to,  preparation  for  sale,
   selling or the  like and Secured  Party's reasonable attorneys'  fees
   and other expenses shall  be payable by Debtor  and shall be  secured
   hereby.  None  of the terms  or provisions of  this Agreement may  be
   waived, altered,  modified  or amended  except  by an  instrument  in
   writing, duly executed by Secured Party and Debtor.  Secured  Party's
   rights and  remedies  hereunder  or  under  any  other  agreement  or
   instrument  shall  be   cumulative,  may  be   exercised  singly   or
   concurrently and are not  exclusive of any  other rights or  remedies
   provided by law.  This Agreement shall be binding on and inure to the
   benefit of the respective  successors and assigns  of the Debtor  and
   Secured Party.    This  Agreement  shall  be  governed  by  the  laws
   governing the Loan Agreement.

   In no event shall interest payable hereunder exceed the highest  rate
   permitted by applicable law.  To the extent any interest received  by
   Lender exceeds the  maximum amount permitted,  such payment shall  be
   credited to principal, and any excess remaining after full payment of
   principal shall be refunded to Maker.  This Note evidences borrowings
   under the  Loan Agreement  and  is secured  by  and entitled  to  the
   benefits of  the  provisions of  the  Loan Agreement  and  any  other
   instruments or  documents  executed  in connection  therewith.    The
   principal of this Note is subject to prepayment in full or in part at
   any time without  premium or penalty;  provided, however, that  Maker
   shall give  Lender at  least five  (5)  business days  prior  written
   notice of any prepayment to permit Lender to exercise its  conversion
   rights as provided in the Loan Agreement prior to such repayment.

   Maker and  all guarantors  and  endorsers hereby  waive  presentment,
   demand, notice,  protest,  and  all  other  demands  and  notices  in
   connection with the delivery, acceptance, performance and enforcement
   of this Note,  and assent  to extensions of  the time  of payment  or
   forbearance or other indulgence without notice.  No delay or omission
   of  Lender  in  exercising  any  right  or  remedy  hereunder   shall
   constitute a  waiver of  any such  right or  remedy.   Acceptance  by
   Lender of any payment  after demand shall not  be deemed a waiver  of
   such demand.  A waiver on one occasion shall not operate as a bar  to
   or waiver of any such right or remedy on any future occasion.

   Executed as  an instrument  under seal  as of  the date  first  above
   written.
